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, GetFileVersionInfo 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.
