A pointer to an MMCKINFO
data structure that is to be filled in as follows:
ckid
Must be the chunk ID of the chunk to create.
If usFlags includes MMIO_CREATERIFF or MMIO_CREATELIST, this field
will be filled in by mmioCreateChunk.
ckSize
Must
be the size of the data portion of the chunk, including the form type or
list type (if any) but not including the 8-byte chunk header or the terminating
null (if any). If this value is not correct when mmioAscend
is called to mark the end of the chunk, then mmioAscend
will seek back and correct the chunk size.
fccType
Must contain the form type or list type, respectively,
if usFlags contains MMIO_CREATERIFF or MMIO_CREATELIST.
ulDataOffset
This field will be filled in on the return from
mmioCreateChunk. It will contain the file offset of the beginning of the
data portion of the chunk.
ulFlags
This
field will be filled in on the return from this mmioCreateChunk. It will
contain the MMIO_DIRTY flag to indicate this chunk was created with mmioCreateChunk.
