pszFileName (PSZ) - input
The name of the RIFF compound file to open.
pmmcfinfo (PMMCFINFO) -
input
A pointer to the MMCFINFO
data structure containing optional header information. It can be NULL.
pmmioinfo (PMMIOINFO) -
input
A pointer to the MMIOINFO
information structure containing optional open information that is passed
to mmioOpen. It can be NULL.
ulFlags (ULONG) - input
Contains none or some of the following flags. The
MMIO_READ, MMIO_WRITE, and MMIO_READWRITE flags are mutually exclusive.
MMIO_READ
Open the file for reading only. This
is the default if MMIO_WRITE and MMIO_READWRITE are not specified.
MMIO_WRITE
Open the file for writing. A file cannot be read
from if the file is opened in this mode.
MMIO_READWRITE
Open the file for both reading and writing.
MMIO_EXCLUSIVE
Open the file with exclusive mode, denying other
processes both read and write access to the file. mmioCFOpen fails if the
file has been opened in any other mode for read or write access, even by
the current process.
MMIO_DENYWRITE
Open
the file and deny other processes write access to the file. mmioCFOpen
fails if the file has been opened by a compatible process or for write access
by any other process.
MMIO_DENYREAD
Open
the file and deny other processes read access to the file. mmioCFOpen fails
if the file has been opened by a compatible process or for read access by
any other process.
MMIO_DENYNONE
Open
the file and deny other processes read access to the file. mmioCFOpen fails
if the file has been opened by a compatible process or for read access by
any other process.
MMIO_CREATE
Directs
mmioCFOpen to create a new file. If the file already exists, it is truncated
to 0 length, unless it is already opened. In that case, a handle (HMMCF)
to the RIFF compound file is returned.
hmmcf (HMMCF) - returns
If the function succeeds, the handle to the RIFF
compound file is returned. A NULL is returned if it fails.
