Creating and Deleting a File
To create a file, set the
dwOpenFlags parameter of the
mmioOpen function to MMIO_CREATE. The following example creates a file and opens it
for reading and writing.
HMMIO hFile;
hFile = mmioOpen("NEWFILE.TXT", NULL, MMIO_CREATE | MMIO_READWRITE);
if (hFile != NULL)
// File created successfully.
else
// File cannot be created.
If the file you are creating already exists, it will be truncated to zero
length.
To delete a file, set the
dwOpenFlags parameter of the
mmioOpen function to MMIO_DELETE. After you delete a file, it cannot be recovered by
any standard means. If your application is deleting a file at the request of a
user, query the user before deleting the file to make sure the user wants to
delete it.
