hmmcf (HMMCF) - input

      A RIFF compound-file handle returned by mmioCFOpen.

    pmmcfinfo (PMMCFINFO) - in/out

      A pointer to the MMCFINFO data structure, which is filled with the CTOC header. This structure is variable in size, and the user must ensure enough memory has been allocated for it.

    cBytes (ULONG) - input

      Size of the buffer that the pmmcfinfo parameter points to. This is the maximum number of bytes that will be copied.

    rc (ULONG) - returns

      Return codes indicating success or type of failure. If the function succeeds, the number of bytes copied is returned. A NULL is returned for a failure. Additional error information is stored in the ulErrorRet field of MMIOINFO as follows:

      MMIOERR_INVALID_PARAMETER

        The parameter passed was invalid. For this function, a NULL pmmcfinfo is invalid. cBytes must be greater than 0.
      MMIOERR_WRITE_ONLY_FILE
        File not opened in read mode.
      MMIOERR_INTERNAL_SYSTEM
        The operation failed due to an internal system error.
