The handle must have the PROCESS_QUERY_INFORMATION and PROCESS_VM_READ access rights

[in, optional] A handle to the module. If this parameter is NULL, this function returns the name of the file used to create the calling process.

[out] A pointer to the buffer that receives the base name of the module. If the base name is longer than maximum number of characters specified by the nSize parameter, the base name is truncated.

If the function succeeds, the return value specifies the length of the string copied to the buffer, in characters.

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

The GetModuleBaseName function is primarily designed for use by debuggers and similar applications that must extract module information from another process. If the module list in the target process is not yet initialized, or if the module list changes during the function call as a result of DLLs being loaded or unloaded, GetModuleBaseName may fail or return incorrect information.

To retrieve the base name of a module in the current process, use the GetModuleFileName function to retrieve the full module name and then use a function call such as strrchr(szmodulename, '\\') to scan to the beginning of the base name within the module name string. This is more efficient and more reliable than calling GetModuleBaseName with a handle to the current process.

To retrieve the base name of the main executable module for a remote process, use the GetProcessImageFileName or QueryFullProcessImageName function to retrieve the module name and then use the strrchr function as described in the previous paragraph. This is more efficient and more reliable than calling GetModuleBaseName with a NULL module handle.

The GetModuleBaseName function does not retrieve the base name for modules that were loaded with the LOAD_LIBRARY_AS_DATAFILE flag. For more information, see LoadLibraryEx.
