mmioSetInfo function

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.

Syntax

MMRESULT mmioSetInfo(
  HMMIO       hmmio,
  LPCMMIOINFO pmmioinfo,
  UINT        fuInfo
);

Parameters

Return Value

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.
