- lptstrFilename
Pointer to a null-terminated filename string that specifies the file of interest.
- dwHandle
This parameter is ignored.
- dwLen
Specifies the size, in bytes, of the buffer pointed to by lpData.
Call the GetFileVersionInfoSize function to determine the size in bytes of a file’s version information. dwLen should be equal to or greater than that value.
If the buffer pointed to by lpData is not large enough, the function truncates the file’s-version information to the size of the buffer.
- lpData
Pointer to a buffer to receive file-version information.
You can use this value in a subsequent call to the VerQueryValue function.
The file version information is always in Unicode format. |
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. |
