mmioCFGetInfo - Parameters

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

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
