If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError.
If the compression algorithm fails for some internal reason, the error from GetLastError can be ERROR_FUNCTION_FAILED. If the system cannot locate the compression algorithm handle, the error can be ERROR_INVALID_HANDLE.
