GetFileVersionInfoSize info  Overview  Group

The GetFileVersionInfoSize function determines whether the operating system can obtain version information about a specified file. If version information is available, GetFileVersionInfoSize returns the size, in bytes, of that information.

As with other file installation functions, GetFileVersionInfoSize works only with Win32 file images. It does not work with 16-bit Windows file images.  

DWORD GetFileVersionInfoSize(

LPTSTR lptstrFilename,	// pointer to filename string
LPDWORD lpdwHandle	// pointer to variable to receive zero
);

Parameters

lptstrFilename

Pointer to a null-terminated filename string that specifies the file of interest.

lpdwHandle

Pointer to a variable that the function sets to zero.

Return Values

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.

Remarks

Call the GetFileVersionInfoSize function before calling the GetFileVersionInfo function. GetFileVersionInfoSize returns the size of the VS_VERSION_INFO structure.
