Determines whether the operating system can retrieve version information for a specified file. If version information is available, GetFileVersionInfoSize returns the size, in bytes, of that information.
Type: LPCTSTR
The name of the file of interest. The function uses the search sequence specified by the LoadLibrary function.
Type: LPDWORD
A pointer to a variable that the function sets to zero.
Type: DWORD
If the function succeeds, the return value is the size, in bytes, of the file's version information.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Call the GetFileVersionInfoSize function before calling the GetFileVersionInfo function. The size returned by GetFileVersionInfoSize indicates the buffer size required for the version information returned by GetFileVersionInfo.
Note
The winver.h header defines GetFileVersionInfoSize as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
