Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

#define INCL_DOSDEVIOCTL
 
USHORT DosDevIOCtl(pfEvents, 0L, 0x0065, 0x0007, hDevice)
