Load Module API

You can use the Load Module API in your code to analyze a module that was loaded in an alternate location that cannot otherwise be tracked by
Intel VTune
Profiler
. For example, this would allow you to analyze code that is typically executed in an isolated environment to which there is no visibility of the code. This API allows you to explicitly set the module location in an address space for analysis by
VTune
Profiler
.
Use This Primitive
To Do This
void
__itt_module_loadW
(void* start_addr,void* end_addr, const wchar_t* path)
Call this function after the relocation of a module. Provide the new start and end addresses for the module and the full path to the module on the local drive.
void
__itt_module_loadA
(void* start_addr, void* end_addr, const char* path)
Call this function after the relocation of a module. Provide the new start and end addresses for the module and the full path to the module on the local drive.
void
__itt_module_load
(void* start_addr, void* end_addr, const char* path)
Call this function after the relocation of a module. Provide the new start and end addresses for the module and the full path to the module on the local drive.

Usage Example

#include "ittnotify.h" __itt_module_load(relocatedBaseModuleAddress, relocatedEndModuleAddress, “/some/path/to/dynamic/library.so”);
