GetModuleFileName

The GetModuleFileName function retrieves the full path and file name for the file containing the specified module.

Windows 95/98: The GetModuleFilename function retrieves long file names when an application's version number is greater than or equal to 4.00 and the long file name is available. Otherwise, it returns only 8.3 format file names.

DWORD GetModuleFileName(
  HMODULE hModule,    // handle to module
  LPTSTR lpFilename,  // file name of module
  DWORD nSize         // size of buffer
);

Parameters

hModule

[in] Handle to the module whose file name is being requested. If this parameter is NULL, GetModuleFileName returns the path for the file containing the current process.

lpFilename

[out] Pointer to a buffer that receives the path and file name of the specified module.

nSize

[in] Specifies the length, in TCHARs, of the lpFilename buffer. If the length of the path and file name exceeds this limit, the string is truncated.

Return Values

If the function succeeds, the return value is the length, in TCHARs, of the string copied to the buffer.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

If a DLL is loaded in two processes, its file name in one process may differ in case from its file name in the other process.
