Call back function when Pin detaches from application in JIT mode

Parameters

[in] v The tool's call-back value.

◆ DETACH_PROBED_CALLBACK

typedef VOID(* DETACH_PROBED_CALLBACK) (VOID *v)

Call back function when Pin detaches from application in Probe mode

Parameters

◆ FETCH_CALLBACK

typedef size_t(* FETCH_CALLBACK) (void *buf, ADDRINT addr, size_t size, EXCEPTION_INFO *pExceptInfo, VOID *v)

Call back function that Pin will use to fetch code bytes to be jitted.

Parameters

[out]	buf	A buffer which receives the fetched instruction bytes. This buffer is at least size bytes long.
[in]	addr	Starting address from which instruction bytes should be fetched.
[in]	size	The number of bytes that should be fetched.
[out]	pExceptInfo	If less than size bytes are fetched, pExceptInfo receives an exception that describes why more bytes could not be fetched. If Pin needs more bytes to decode the next instruction, this exception will be delivered to the application.
[in]	v	The tool's call-back value.

Returns: The number of bytes sucessfully fetched into buf. This may be less than size (or even zero) if Pin attempts to fetch instructions from an invalid address.

◆ FINI_CALLBACK

typedef VOID(* FINI_CALLBACK) (INT32 code, VOID *v)

Call back function when application exits. It is called after all the per thread fini functions were called (registered via PIN_AddThreadFiniFunction). This function may be called on any application thread or internal thread spawned by the tool.

@Note It is prohibited to access the TLS in this callback.

Parameters

[in]	code	O/S specific termination code for the application.
[in]	v	The tool's call-back value.

◆ FORK_CALLBACK

typedef VOID(* FORK_CALLBACK) (THREADID threadid, const CONTEXT *ctxt, VOID *v)

Call-back function when the application forks.

Parameters

[in]	threadId	Thread index
[in]	ctxt	Register state immediately before/after the fork.

Parameters

[in]	tid	The Pin thread ID of the thread that handled the signal.
[in]	sig	The signal number.
[in,out]	ctxt	The application's register state when it was interrupted by the signal. The tool may change this context if desired. If so, the application continues at the modified context. Or, if the application's signal handler is invoked, the handler is passed the modified context for its return context.
[in]	hasHandler	TRUE if the application has a handler registered for this signal.
[in]	pExceptInfo	If the signal represents an exception, pExceptInfo points to a description of the exception. If the signal is not an exception, pExceptInfo is NULL.
[in]	v	The tool's call-back value.

Returns: Returning TRUE tells Pin to pass the signal on to the application. Returning FALSE tells Pin to squash the signal and execution resumes at ctxt.

◆ INTERNAL_EXCEPTION_CALLBACK

typedef EXCEPT_HANDLING_RESULT(* INTERNAL_EXCEPTION_CALLBACK) (THREADID tid, EXCEPTION_INFO *pExceptInfo, PHYSICAL_CONTEXT *pPhysCtxt, VOID *v)

Pin client interface and implementation for internal exception handling

Handler (call-back) function when pin/tool generates internal exception. This function can be registered via PIN_AddInternalExceptionHandler() or PIN_TryStart(). This function becomes active only after APPLICATION_START_CALLBACK notification is delivered. Any internal exception prior to this event can't be handled.

If the exception occurred while analysis routine is executed, it is legal to modify the execution control path using functions such as PIN_RaiseException() or PIN_ExecuteAt(). In this case, any per-thread INTERNAL_EXCEPTION_CALLBACK function registered via PIN_TryStart() will be unregistered automatically (similar semantics to PIN_TryEnd() for all registered notifications)

Note: It is unsupported to call PIN_CallApplicationFunction() in the scope of this callback

Parameters

[in]	tid	The Pin thread ID of the thread that generated the exception.
[in,out]	pExceptInfo	Pointer to the EXCEPTION_INFO structure that describes the exception. If the exception should be raised in the context of the application (using PIN_RaiseException()), The tool should update the exception info to match the OS logic (e.g. update exception address using PIN_SetExceptionAddress()).
[in,out]	pPhysCtxt	Physical register state when the exception was generated. The tool can change pPhysCtxt (make sure that if PIN_TryStart() was called, matching PIN_TryEnd() will be called)
[in]	v	The tool's call-back value.

Returns: an EXCEPT_HANDLING_RESULT value

◆ MEMORY_ADDR_TRANS_CALLBACK

typedef ADDRINT(PIN_FAST_ANALYSIS_CALL* MEMORY_ADDR_TRANS_CALLBACK) (PIN_MEM_TRANS_INFO *memTransInfo, VOID *v)

Call back function for pin/tool to modify memory address arguments in analysis routines. This feature allows users to register for a callback immediately prior to an analysis routine which gets one of the four IARG_MEMORY*_PTR as a parameter. The callback enables the user to manipulate the memory address pointed to by the aforementioned parameter. This function can be registered via PIN_AddMemoryAddressTransFunction(). This function is called from the jitted code, so calls to this function are not serialized.

Parameters

[in]	memTransInfo	Memory address data structure
[in]	v	The tool's call-back value

◆ OUT_OF_MEMORY_CALLBACK

typedef VOID(* OUT_OF_MEMORY_CALLBACK) (size_t size, VOID *v)

Call back function when pin/tool is out of memory. This function can be registered via PIN_AddOutOfMemoryFunction().

Parameters

[in]	size	Size of the failed allocation
[in]	v	The tool's call-back value

◆ PIN_CONFIGURATION_INFO

typedef VOID* PIN_CONFIGURATION_INFO

Global configuration for Pin. Currently, this configuration includes whether Pin should serialize calls to some callbacks (for backward compatibility) or if it should concurrently call the callbacks (better for multi-threaded performance).

Note: A new instance of PIN_CONFIGURATION_INFO with default values should be created with PIN_CreateDefaultConfigurationInfo()

◆ PREPARE_FOR_FINI_CALLBACK

typedef VOID(* PREPARE_FOR_FINI_CALLBACK) (VOID *v)

Call back function invoked when Pin is about to detach from terminating process. The function that is registered by this callback may gracefully finish all the internal threads of the tool, e.g.

Force all the internal threads of the tool to finish using return from the main function of the thread or calling PIN_ExitThread.
Wait until all the internal threads are finished before it will continue to run. @Note: normal run of the internal threads after exit from all registered call back functions of this type is not guaranteed. @Note: If current thread is an internal thread, do not finish it in this callback!

This function is invoked in thread that initiated process termination. This function is registered via PIN_AddPrepareForFiniFunction().

Parameters

[in] v The tool's call-back value

◆ REMOVE_INSTRUMENTATION_CALLBACK

typedef VOID(* REMOVE_INSTRUMENTATION_CALLBACK) (VOID *v)

Call back function when Pin removes all old instrumented code from its cache

◆ THREAD_ATTACH_PROBED_CALLBACK

typedef VOID(* THREAD_ATTACH_PROBED_CALLBACK) (VOID *sigmask, VOID *v)

Call-back function when an attached thread starts to run under Pin in probe mode. The tool receives the signal mask at the attach point and can modify it. The changes to this value will be applied when the thread continues to run. Pin does not validate the new signal mask so tools must take extra care when modifying this value.

Parameters

[in,out]	sigmask	The thread's signal mask at the attach point. The tool may change this and affect the signal mask once the thread starts running again.
[in]	v	The tool's call-back value.

◆ THREAD_DETACH_CALLBACK

typedef VOID(* THREAD_DETACH_CALLBACK) (THREADID threadIndex, const CONTEXT *ctxt, VOID *v)

[in]	v	The tool's call-back value.

◆ THREAD_DETACH_PROBED_CALLBACK

typedef VOID(* THREAD_DETACH_PROBED_CALLBACK) (VOID *v)

Call-back function before an application thread is being detached from Pin in probe mode. The callback is received in the thread native context before probes removal.

Function Documentation

◆ PIN_AddApplicationStartFunction()

PIN_CALLBACK PIN_AddApplicationStartFunction	(	APPLICATION_START_CALLBACK	fun,
		VOID *	val
	)

Register a notification function that is called after pin initialization is finished. This notification function is available when pin launches the application and when pin attaches to a running process.

On Unix (Linux & macOS*): This notification function is called on the application's main thread (both launch & attach mode). This notification is called right before Pin resume the application.

On Windows: When pin launches the application, this notification function is called on the application's main thread. When pin attaches to a running process, this notification function is called on a dedicated thread which is not part of the application's threads.
When it is called, all the application's threads are paused by Pin and are about to be released.
No new threads can be created by the application at this time.

When Pin starts running a program, it calls into the tool several times in the following order:

Calls the tool's main() function.
If the tool set up a notification with IMG_AddInstrumentFunction(), Pin calls this call-back for each image that is already loaded in the application's address space at the point when Pin attaches to it.
Calls any notification call-backs set up with PIN_AddApplicationStartFunction().

Parameters

[in] fun Function to be called at application start.

[in] val Value to pass to the function.

Returns
PIN_CALLBACK A handle to a callback that can be used to further modify this callback's properties

Note
The pin client lock is obtained during the call of this API.

PIN_CALLBACK PIN_AddDetachFunction	(	DETACH_CALLBACK	fun,
		VOID *	val
	)

Call func immediately before Pin relinquishes control of the application through PIN_Detach().

At this stage no more instrumentation/analysis callbacks will be called

This function is called one time for the process. It may be called by any thread. Pin memory is not freed at this moment.

Parameters

fun	Call back function to execute before detaching
val	Value to be passed to fun when it is called

PIN_CALLBACK PIN_AddDetachFunctionProbed	(	DETACH_PROBED_CALLBACK	fun,
		VOID *	val
	)

Register a notification function that is called immediately after Pin relinquishes control of the application through PIN_DetachProbed(). There can be more than one Detach callback function.
When this callback function is called, it is guaranteed that Pin removed all probes from the application code and that no other callback function will be called afterwards (except from additional Detach callback functions).

Parameters

fun	Call back function to execute before detaching
val	Value to be passed to fun when it is called

Returns: PIN_CALLBACK A handle to a callback that can be used to further modify this callback's properties

◆ PIN_AddFetchFunction()

VOID PIN_AddFetchFunction	(	FETCH_CALLBACK	fun,
		VOID *	val
	)

Called to register a function That will become the function that Pin calls to fetch application instructions. Pin sometimes attempt to fetch instructions from an invalid address, and the call-back needs to handle this correctly. If multiple functions are registered using this API, only the last one registered is used

Pin cannot automatically detect self-modifying code (SMC) when a tool uses this API. Therefore, such tools take over responsibility for detecting SMC and must explicitly regenerate all traces within a modified code range if such was detected using PIN_RemoveInstrumentationInRange.

Parameters

[in]	fun	The tool's call-back function.
[in]	val	The tool's call-back value.

◆ PIN_AddInternalExceptionHandler()

PIN_CALLBACK PIN_AddInternalExceptionHandler	(	INTERNAL_EXCEPTION_CALLBACK	fun,
		VOID *	val
	)

Register a global (not per-thread) notification handler function that is called upon receipt of any unhandled internal exception in Pin or the tool. This handler does not catch exceptions that are generated by the application, nor does it catch exceptions that are handled by PIN_TryStart() / PIN_TryEnd(). The handler is active for all the application's threads, it should be called in tool's main() before PIN_StartProgram(). If it is called after PIN_StartProgram() is called, it will be ignored. The user can register up to MAX_IEH_CALLBACKS global notification functions.

Note: This function should be used for permanent global call-back registration (as opposed to PIN_TryStart() / PIN_TryEnd() pair which should be used for function scope registration).

Parameters

[in]	fun	Handler function to execute upon receipt of internal exception in pin/tool.
[in]	val	Value to pass to the function.

Returns: PIN_CALLBACK A handle to a callback that can be used to further modify this callback's properties

Register a notification function that is called when pin/tool is out of memory.
Try to reduce memory consumption when this notification function is called.
Any implicit or explicit usage of malloc()/realloc() etc. in this notification function might cause an infinite recursion.
The call to the notification function is NOT serialized by pin. The user can't assume anything about the locks state while the notification is delivered (as out of memory condition can occur anywhere). Avoid dead-locks by careful design of the notification function.
A tool can register only one notification function.
A new notification function registration overwrites any previous registration.
To disable the notification function, pass a NULL function pointer.

Parameters

fun	Call back function is passed the size of the failing allocation

◆ PIN_AddThreadAttachFunction()

PIN_CALLBACK PIN_AddThreadAttachFunction	(	THREAD_ATTACH_CALLBACK	fun,
		VOID *	val
	)

This API is useful when Pin is run in JIT mode and attaches to a running process. Tools may use this API to register a notification that is called by each application thread.

After Pin attaches to the process, Pin first notifies the tool of any images that are loaded (see IMG_AddInstrumentFunction()) and then notifies the tool that initialization is complete (see PIN_AddApplicationStartFunction()). After that, each thread in the application calls the notification set up by PIN_AddThreadAttachFunction(). After each thread returns from this notification, it resumes execution in the application code.

Note, this notification happens only for threads that exist in the process at the time that Pin attaches.

It does not happen for the following threads:

Threads that are created in the process after Pin is already attached.
Internal threads spawned by Pin tool when Pin re-attaches to the application.

Parameters

[in]	fun	Call-back function to execute for the attached thread.
[in]	val	Value to pass to the function.

Returns: PIN_CALLBACK A handle to a callback that can be used to further modify this callback's properties

This API is useful when Pin is run in probe mode and attaches to a running process. Tools may use this API to register a notification that is called by each application thread.

After Pin attaches to the process, Pin first notifies the tool of any images that are loaded (see IMG_AddInstrumentFunction()) and then notifies the tool that initialization is complete (see PIN_AddApplicationStartFunction()). After that, each thread in the application calls the notification set up by PIN_AddThreadAttachProbedFunction(). After each thread returns from this notification, it resumes execution in the application code.

Note, this notification happens only for threads that exist in the process at the time that Pin attaches. It does not happen for threads that are created in the process after Pin is already attached.

Parameters

[in]	fun	Call-back function to execute for the attached thread.
[in]	val	Value to pass to the function.

◆ PIN_CallApplicationFunction()

VOID PIN_CallApplicationFunction	(	const CONTEXT *	ctxt,
		THREADID	tid,
		CALLINGSTD_TYPE	cstype,
		AFUNPTR	origFunPtr,
		CALL_APPLICATION_FUNCTION_PARAM *	param,
			...
	)

This API allows a tool to call a function inside the application. The function is executed under control of Pin's JIT compiler, and the application code is instrumented normally. Tools should not make direct calls to application functions when Pin is in JIT mode.

PIN_CallApplicationFunction() can be called from a replacement routine or an analysis routine, but not from a call-back. Note that this API can result in recursive execution in the tool since the called application function is also instrumented.

One usage model for this API is to "wrap" an application function, executing analysis code before the function is called and after it returns. To do this, use RTN_ReplaceSignature() to replace the application function, use IARG_ORIG_FUNCPTR to pass the original function pointer to the replacement routine, and use IARG_CONST_CONTEXT to pass the register state. You can then call back on the original function from your replacement routine with PIN_CallApplicationFunction(). Note, however, that the overhead of PIN_CallApplicationFunction() can be high, so it is more efficient to use *_InsertCall() instead if possible.

Parameters

[in]	ctxt	The application register state to use when calling the function. Pin changes the register state in order to pass arguments to the function, but the ctxt parameter isn't changed.
[in]	tid	The Pin id of the current thread (see IARG_THREAD_ID).
[in]	cstype	The calling standard used for calling this function (CALLINGSTD_DEFAULT recommended).
[in]	origFunPtr	The entry point of the application function.
[in]	param	Additional parameters to define the exact behavior of this function invocation (or NULL for using the defaults). See CALL_APPLICATION_FUNCTION_PARAM .
[in]	...	List of function argument type and size.

See PIN_PARG for the recommended method of passing function arguments. PIN_PARG_END() must end the argument list, even if the function has no arguments. If the application function has a return value, it must appear first in the argument list.

◆ PIN_Detach()

VOID PIN_Detach ( )

Pin relinquishes control of the application and the original un-instrumented code is executed.

On Linux, the function may be invoked from analysis, instrumentation or callback routines. It may be executed by any thread, including threads spawned by the Pintool which are invisible to the Pin VM.

On Windows and macOS*, the function must be invoked from an analysis routine. Invoking the function from instrumentation routines could cause Pin to misbehave. See Tests/detach.C for an example of its use.

The request for detach is considered by Pin as asynchronous. This means that Pin will perform the detach procedure at a point which it considers convenient to do so. From the user's perspective, instrumentation, analysis or callback routines might still be executed after calling PIN_Detach(). In practice, PIN_Detach() simply registers the request to the Pin VM and exits immediately i.e. the function does not wait for detach to complete.

Once Pin starts the detach procedure, it can't be blocked, and will not run forever. It is not possible to detach one thread. All threads will run natively after PIN_Detach(). During detach, Pin doesn't free memory used for Pin objects. This memory will be used during re-attach.

During the detach procedure Pin runs an auxiliary process, which communicates with the running application process via debug interface. The auxiliary process is temporary and will exit immediately when the detach procedure is completed. For the user, this means that a debugger cannot be attached to the application process during detach.

Use PIN_AddDetachFunction() to receive a notification just prior to detach. The callback will be received after all the threads are stopped inside the VM and no more instrumentation functions, analysis routines or callbacks will be called.
Note: at this point, the auxiliary process mentioned above is still attached to the application process.

◆ PIN_DetachProbed()

VOID PIN_DetachProbed ( )

Initiate Pin detach request in probe mode. In the scope of this operation, Pin removes all probes set by Pin & tool, The user can get a notification when the detach operation has been completed (via callback registration using PIN_AddDetachFunctionProbed()). On Linux, the user can get additional per-thread callbacks just prior to probes removal. (via callback registration using PIN_AddThreadDetachProbedFunction()).These callbacks will be given for each thread in its native context. If Pin has already detached (using PIN_DetachProbed()), or if Pin has not fully started yet (the notification function registered by PIN_AddApplicationStartFunction() was not yet delivered to the tool), this function will be ignored.

Note: Even though Pin removes all probes, replacement functions can still be active (for example, if the replacement function is still located on the call stack of one of the threads). It is the tool responsibility to handle these scenarios.; The vm and pin client locks are obtained during the call of this API.

◆ PIN_InterceptSignal()

BOOL PIN_InterceptSignal	(	INT32	sig,
		INTERCEPT_SIGNAL_CALLBACK	fun,
		VOID *	val
	)

Establish an interceptor function for signals delivered to the application. Tools should never call sigaction() directly to handle signals. The interceptor function is called whenever the application receives the requested signal, regardless of whether the application has a handler for that signal. The tool's handler can then decide whether the signal should be forwarded to the application.

There are two intended usage models for this API, which are both advanced features. If your tool merely needs to be notified of signals that are sent to the application, use PIN_AddContextChangeFunction() instead.

In one usage model, a tool can take over ownership of a signal in order to use the signal as an asynchronous communication mechanism to the outside world. For example, if a tool intercepts SIGUSR1, a user of the tool could send this signal and tell the tool to do something. In this usage model, the tool may want to call PIN_UnblockSignal() so that it will receive the signal even if the application attempts to block it.

In the second usage model, the tool may need to "squash" certain signals that the application generates. For example, a tool that forces speculative execution in the application may want to intercept and squash exceptions generated in the speculative code.

A tool can set only one "intercept" handler for a particular signal, so a new handler overwrites any previous handler for the same signal. To disable a handler, pass a NULL function pointer.

Parameters

[in]	sig	The signal number to intercept, which may not be SIGKILL or SIGSTOP.
[in]	fun	The tool's intercept function, or NULL.
[in]	val	Value to pass to the intercept function.

Returns: TRUE on success (always FALSE on Windows).

◆ PIN_SafeCopy()

size_t PIN_SafeCopy	(	VOID *	dst,
		const VOID *	src,
		size_t	size
	)

Copy the specified number of bytes from a source memory region to a destination memory region. The function guarantees safe return to the caller even if the source or destination regions are inaccessible (entirely or partially).

Tools should use this function to ensure safe access to the original content of the application's memory. For example, on Windows, Pin replaces certain TEB fields when running analysis routines in the tool. If the tool accesses these fields directly, it would see the values assigned by Pin rather than the original ones. On the contrary, PIN_SafeCopy() always reads and modifies the original application's values of these fields.

This function can be used in any thread, including any internal thread spawned by the tool.

Parameters

[out]	dst	destination region
[in]	src	region to copy from
[in]	size	number of bytes to copy

Returns: Number of bytes successfully copied from the source to the destination region.

Note: PIN_SafeCopy() should not be called before the application has been started. For instance, it cannot be called in an Image load callback. Unexpected results will occur.

◆ PIN_SafeCopyEx()

size_t PIN_SafeCopyEx	(	VOID *	dst,

Copy the specified number of bytes from a source memory region to a destination memory region. The function guarantees safe return to the caller even if the source or destination regions are inaccessible (entirely or partially).

In addition to the PIN_SafeCopy functionality, this function allows the tool to obtain detailed exception information in case of failure.

This function can be used in any thread, including any internal thread spawned by the tool.

Parameters

[out]	dst	destination region
[in]	src	region to copy from
[in]	size	number of bytes to copy
[out]	pExceptInfo	pointer to the structure that receives the exception information in case of failure.

Returns: Number of bytes successfully copied from the source to the destination region. If the function fails to copy all bytes, it provides detailed description of the failure in the <pExceptInfo> structure.

Note: The exception address in the returned exception information always has zero value. If the tool wants to raise this exception on behalf of the application, it should use PIN_SetExceptionAddress function to set an appropriate exception address before passing the exception information to the PIN_RaiseException function.; PIN_SafeCopyEx() should not be called before the application has been started. For instance, it cannot be called in an Image load callback. Unexpected results will occur.

◆ PIN_SetAllowedConcurrentCallbacks()

VOID PIN_SetAllowedConcurrentCallbacks	(	PIN_CONFIGURATION_INFO	options,
		PIN_CALLBACK_TYPE	callbackType
	)

Enables/disables concurrent delivery of certain callbacks in a specific PIN_CONFIGURATION_INFO instance.

Parameters

options The PIN_CONFIGURATION_INFO instance to modify.

callbackType Specifies which Pin callbacks are allowed to be delivered concurrently:

In the case where a callback should be delivered to several threads at a given moment, delivering a callback concurrently means that each thread is free to deliver its the respective callbacks without waiting for the other threads. This means that Pin doesn't acquire any exclusive internal lock in order to deliver a concurrent callback

In constrast, delivering a callback in a serialized way means that, in a given moment, only one threads is allowed to deliver any type of callback. Serializing the callback might hurt the performance of your Pin tool, but it will protect the tool against possibly race conditions in your tool. When a callback is considered "serialized", Pin will acquire an exclusive internal lock before delivering the callback to the tool.

Note: In order for this option to take effect the PIN_CONFIGURATION_INFO must be passed to PIN_StartProgram().; Currently, other types of callbacks (which don't have a respective enum entry in PIN_CALLBACK_TYPE) are serialized by Pin with no option to change that.

◆ PIN_SetReplayMode()

VOID PIN_SetReplayMode ( UINT32 flags )

Tell Pin to execute different sets of operations in replay mode.

The only flag currently supported is REPLAY_MODE_IMAGEOPS which disables Pin's normal detection of image load and unload events, which are expected to be replayed through the IMG_ReplayImageLoad and IMG_ReplayImageUnload calls. It also avoids Pin loading information about the initial image given on the command line.

Other flags may be added as required in the future.

Must be called before PIN_StartProgram

Parameters

flags A mask created from the PIN_REPLAY_MODE_FLAGS enum describing the operations the replayer will take control of.

◆ PIN_SetSmcSupport()

VOID PIN_SetSmcSupport ( SMC_ENABLE_DISABLE_TYPE enable_disable )

Enable/Disable Pin's support of self modifying code When enabled, Pin will detect self modification of code and will deliver a callback, if one is registered, when such an event happens. When disabled and if SMC occurs, the SMC will not be detected and the original code will continue to execute. This function takes precedence over the specification of smc_support in the invocation line. This function must be called before PIN_StartProgram.

Parameters

[in] enable SMC_ENABLE, or SMC_DISABLE

SMC support is enabled by default

◆ PIN_StartProgram()

VOID PIN_StartProgram ( PIN_CONFIGURATION_INFO options = PIN_CreateDefaultConfigurationInfo() )

Starts executing the application, when Pin is in JIT mode, which is the default. Note that PIN_Init() must be called before PIN_StartProgram().

Parameters

options Pin global configuration to use in this run of Pin. These configuration options are set only once (during the call of PIN_StartProgram()), and they are affecting the entire execution of Pin.

Note: The PIN_StartProgram() function never returns. It also unwinds the tool's stack, so any local (stack based) variables are lost.; The vm and pin client locks are obtained during the call of this API.

◆ PIN_StartProgramProbed()

VOID PIN_StartProgramProbed ( )

Starts executing the application, when Pin is in Probe mode. Note that PIN_Init() must be called before PIN_StartProgramProbed().

The PIN_StartProgramProbed() function never returns. It also unwinds the tool's stack, so any local (stack based) variables are lost.

Note: The vm and pin client locks are obtained during the call of this API.

◆ PIN_ToolFullPath()

const CHAR* PIN_ToolFullPath ( )

Returns full path of main Pin tool binary image, encoded in UTF8 (superset of ASCII).

◆ PIN_TryEnd()

VOID PIN_TryEnd ( THREADID tid )

Unregister the last registered notification function (registered via PIN_TryStart()) from the context of the calling thread. This function should be called in the same function scope as the previously registered .\n This function can be used in any thread, including any internal thread spawned by the tool.

Parameters

[in] tid Id of the calling thread.

◆ PIN_TryStart()

VOID PIN_TryStart	(	THREADID	tid,
		INTERNAL_EXCEPTION_CALLBACK	fun,
		VOID *	val
	)

Register a per-thread notification handler function that is called upon receipt of an internal exception in pin or the tool in the context of the calling thread. Use PIN_TryEnd() in order to remove the registered handler from the context of the calling thread (do it in the same function scope). The user can register up to MAX_IEH_CALLBACKS per-thread notification functions.
This function can be used in any thread, including any internal thread spawned by the tool.

Note: It is unsupported to call PIN_CallApplicationFunction() in the scope of PIN_TryStart() / PIN_TryEnd() pair.

Parameters

[in]	tid	Id of the calling thread.
[in]	fun	Handler function to execute upon receipt of internal exception in pin/tool.
[in]	val	Value to pass to the handler function.

◆ PIN_UnblockSignal()

BOOL PIN_UnblockSignal	(	INT32	sig,
		BOOL	enable
	)

This API is normally used in conjunction with PIN_InterceptSignal() to prevent the application from blocking a signal that the tool intercepts. This is useful if the tool wants to ensure that the application will not prevent the tool from receiving the intercepted signal.

When this API is called before PIN_StartProgram(), it affects all threads in the application. However, if it is called after PIN_StartProgram(), it only affects the calling thread. If the application spawns a thread, the child thread inherits the signal blocking state from its parent.

Tools should take care when using this API because it can adversely affect the application if it also uses the signal sig.

Parameters

[in]	sig	The signal number, which may not be SIGKILL or SIGSTOP.
[in]	enable	If TRUE, the application is prevented from blocking sig. If FALSE, the application may block or unblock sig at will.

Returns: TRUE on success (always FALSE on Windows).

Note: The pin client lock is obtained during the call of this API.

◆ PIN_UnlockClient()

VOID PIN_UnlockClient ( )

Some Pin API functions may be called only when the thread is holding this lock. See also PIN_LockClient.
This function can be used in any thread, including any internal thread spawned by the tool.

◆ PIN_Version()

const std::string& PIN_Version ( )

Returns a fully descriptive Pin version string, including the Intel copyright notice. The returned version is the Pin version that the tool was linked with.

◆ PIN_VmFullPath()

CHAR* PIN_VmFullPath ( )

Returns full path of Pin binary invoked, encoded in UTF8 (superset of ASCII), this is supported for Linux (only for locales encoded in UTF8).

Availability:: Mode: JIT
O/S: Linux & macOS*
CPU: All

[in]	fun	Function to be called at application start.
[in]	val	Value to pass to the function.
