Retrieves the module information of the specified module.
BOOL IMAGEAPI SymGetModuleInfo( HANDLE hProcess, DWORD dwAddr, PIMAGEHLP_MODULE ModuleInfo );
A handle to the process that was originally passed to the SymInitialize function.
The virtual address that is contained in one of the modules loaded by the SymLoadModule64 function
A pointer to an IMAGEHLP_MODULE64 structure. The SizeOfStruct member must be set to the size of the IMAGEHLP_MODULE64 structure. An invalid value will result in an error.
If the function succeeds, the return value is TRUE.
If the function fails, the return value is FALSE. To retrieve extended error information, call GetLastError.
The module table is searched for a module that contains the dwAddr. The module is located based on the load address and size of each module. If a valid module is found, the ModuleInfo parameter is filled with the information about the module.
The size of the IMAGEHLP_MODULE64 structure used by this function has changed over the years. If a version of DbgHelp.dll is called that is older than the DbgHelp.h used to compile the calling code, then this function may fail with an error code of ERROR_INVALID_PARAMETER. This most commonly occurs when the system version (%WinDir%\System32\DbgHelp.dll) is called. Code that calls the system version of DbgHelp.dll must be compiled using the appropriate SDK for that Windows release or the SDK for a previous release.
The recommended model is to redistribute the required version of DbgHelp.dll along with the calling software. This allows the caller to use the most robust versions of DbgHelp.dll as well as a simplifying upgrades. The most recent version of DbgHelp.dll can always be found in the Debugging Tools for Windows package. As a general rule, code that is compiled to work with older versions will always work with newer versions.
All DbgHelp functions, such as this one, are single threaded. Therefore, calls from more than one thread to this function will likely result in unexpected behavior or memory corruption. To avoid this, you must synchronize all concurrent calls from more than one thread to this function.
To call the Unicode version of this function, define DBGHELP_TRANSLATE_TCHAR. SymGetModuleInfoW64 is defined as follows in DbgHelp.h.
BOOL IMAGEAPI SymGetModuleInfoW64( __in HANDLE hProcess, __in DWORD64 qwAddr, __out PIMAGEHLP_MODULEW64 ModuleInfo );
#if !defined(_IMAGEHLP_SOURCE_) && defined(_IMAGEHLP64) #define SymGetModuleInfo SymGetModuleInfo64 #define SymGetModuleInfoW SymGetModuleInfoW64 #else BOOL IMAGEAPI SymGetModuleInfo( __in HANDLE hProcess, __in DWORD dwAddr, __out PIMAGEHLP_MODULE ModuleInfo );
