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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.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, 0x0065, 0x0008, hDevice)
PBYTE pbCommand;    /* pointer to structure with command */
HFILE hDevice;      /* device handle                     */
 
The DSK_VERIFYTRACK function verifies an operation on a specified disk
drive.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
pbCommand  Points to the TRACKLAYOUT structure that contains information
           about the verification operation.
 
hDevice    Identifies the disk drive that receives the device-control
           function. The handle must have been created previously by using
           the DosOpen function.
 
Return Value
 
The return value is zero if the function is successful or an error value if
an error occurs.
 
Comments
 
The track-layout table passed in the function determines the sector number,
which is passed to the disk controller. When the sectors are odd-numbered or
nonconsecutive, the request is broken into an appropriate number of
single-sector operations, and one sector at a time is verified.
