MMRESULT mmioAscend( HMMIO hmmio, LPMMCKINFO lpck, UINT wFlags );
File handle of an open RIFF file.
Reserved; must be zero.
Returns MMSYSERR_NOERROR if successful or an error otherwise. Possible error values include the following.
|MMIOERR_CANNOTSEEK||There was an error while seeking to the end of the chunk.|
|MMIOERR_CANNOTWRITE||The contents of the buffer could not be written to disk.|
If the chunk was descended into by using mmioDescend, mmioAscend seeks to the location following the end of the chunk (past the extra pad byte, if any).
If the chunk was created and descended into by using mmioCreateChunk, or if the MMIO_DIRTY flag is set in the dwFlags member of the MMCKINFO structure referenced by lpck, the current file position is assumed to be the end of the data portion of the chunk. If the chunk size is not the same as the value stored in the cksize member of the MMCKINFO structure when mmioCreateChunk was called, mmioAscend corrects the chunk size in the file before ascending from the chunk. If the chunk size is odd, mmioAscend writes a null pad byte at the end of the chunk. After ascending from the chunk, the current file position is the location following the end of the chunk (past the extra pad byte, if any).
