Detailed Description

This section describes the base class used for initializing the encoder / decoder requests and the XED library initialization function.

All XED functions reside in the XED namespace. To use XED, you must include "xed-interface.h" and then use the name space:

    #include "xed-interface.h"

If you are calling XED2 from C++, you must wrap this include:

    extern "C" {
    #include "xed-interface.h"
    }

Once, before using XED, you must call xed_tables_init() to initialize the tables XED uses for encoding and decoding:

    xed_tables_init();

Once initialized, XED is reentrant (multithread safe). All values used for encoding and decoding live on the caller's stack or in the passed-in parameters.

If your program is multithreaded, initialize XED once (and only once) using the above call before you attempt to decode or encode from any thread. Each thread does NOT need to initialize XED. The idea is to initialize XED before creating your threads.


Typedef Documentation

typedef struct xed_state_s xed_state_t
 

Encapsulates machine modes for decoder/encoder requests.

It specifies the machine operating mode as a xed_machine_mode_enum_t for decoding and encoding. The machine mode corresponds to the default data operand width for that mode. For all modes other than the 64b long mode (XED_MACHINE_MODE_LONG_64), a default addressing width, and a stack addressing width must be supplied of type xed_address_width_enum_t .


Function Documentation

XED_DLL_EXPORT char const* xed_get_copyright void   ) 
 

Returns a copyright string.

XED_DLL_EXPORT char const* xed_get_version void   ) 
 

Returns a string representing XED svn commit revision and time stamp.

XED_DLL_EXPORT void xed_register_abort_function xed_user_abort_function_t  fn,
void *  other
 

This is for registering a function to be called during XED's assert processing.

If you do not register an abort function, then the system's abort function will be called. If your supplied function returns, then abort() will still be called.

Parameters:
fn This is a function pointer for a function that should handle the assertion reporting. The function pointer points to a function that takes 4 arguments: (1) msg, the assertion message, (2) file, the file name, (3) line, the line number (as an integer), and (4) other, a void pointer that is supplied as thei 2nd argument to this registration.
other This is a void* that is passed back to your supplied function fn as its 4th argument. It can be zero if you don't need this feature. You can used this to convey whatever additional context to your assertion handler (like FILE* pointers etc.).

xed_address_width_enum_t  arg_stack_addr_width
[static]
 

Constructor.

DEPRECATED: use xed_state_init2(). The mode, and addresses widths are enumerations that specify the number of bits. In 64b mode (XED_MACHINE_MODE_LONG_64) the address width and stack address widths are 64b (XED_ADDRESS_WIDTH_64b). In other machine modes, you must specify valid addressing widths.

Parameters:
p the pointer to the xed_state_t type
arg_mmode the machine mode of type xed_machine_mode_enum_t
arg_ignored Ignored. The addressing width is now implied by the machine mode implied by arg_mmmode.
arg_stack_addr_width the stack address width of type xed_address_width_enum_t (only required if not the mode is not XED_MACHINE_MODE_LONG_64)

Constructor.

The mode, and addresses widths are enumerations that specify the number of bits. In 64b mode (XED_MACHINE_MODE_LONG_64) the address width and stack address widths are 64b (XED_ADDRESS_WIDTH_64b). In other machine modes, you must specify valid addressing widths.

Parameters:
p the pointer to the xed_state_t type
arg_mmode the machine mode of type xed_machine_mode_enum_t
arg_stack_addr_width the stack address width of type xed_address_width_enum_t (only required if not the mode is not XED_MACHINE_MODE_LONG_64)
