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.
