The mmioSetInfo function updates the information retrieved by the mmioGetInfo function about a file opened by using the mmioOpen function. Use this function to terminate direct buffer access of a file opened for buffered I/O.
MMRESULT mmioSetInfo( HMMIO hmmio, LPCMMIOINFO pmmioinfo, UINT fuInfo );
File handle of the file.
Returns zero if successful or an error otherwise.
If you have written to the file I/O buffer, set the MMIO_DIRTY flag in the dwFlags member of the MMIOINFO structure before calling mmioSetInfo to terminate direct buffer access. Otherwise, the buffer will not get flushed to disk.
