SymUnloadModule function (dbghelp.h)
Unloads the symbol table.
Syntax
BOOL IMAGEAPI SymUnloadModule(
[in] HANDLE hProcess,
[in] DWORD BaseOfDll
);
Parameters
[in] hProcess
A handle to the process that was originally passed to the SymInitialize function.
[in] BaseOfDll
The base address of the module that is to be unloaded.
Return value
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.
Remarks
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.
This function supersedes the SymUnloadedModule function. For more information, see Updated Platform Support. SymUnloadedModule is defined as follows in Dbghelp.h.
#if !defined(_IMAGEHLP_SOURCE_) && defined(_IMAGEHLP64)
#define SymUnloadModule SymUnloadModule64
#else
BOOL
IMAGEAPI
SymUnloadModule(
__in HANDLE hProcess,
__in DWORD BaseOfDll
);
#endif
Examples
For an example, see Unloading a Symbol Module.
