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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.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(0L, pbCommand, 0x0001, 0x0008, hDevice)
PBYTE pbCommand;    /* pointer to variable with command */
HFILE hDevice;      /* device handle                    */
 
The DSK_UNLOCKDRIVE function unlocks a drive. The drive requires the locked
volume represented by the handle.
