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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.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, 0x0009, hDevice)
PBYTE pbCommand;    /* pointer to structure with verification data */
HFILE hDevice;      /* device handle                               */
 
The PDSK_VERIFYPHYSTRACK function verifies I/O on a physical track on the
device specified in the request.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
pbCommand  Points to the TRACKLAYOUT structure that contains information
           about the verify operation.
 
hDevice    Identifies the physical device that receives the device-control
           function. The handle must have been created previously by using
           the DosPhysicalDisk function.
 
Return Value
 
The return value is zero if the function is successful or an error value if
an error occurs.
 
Comments
 
This function is similar to the DSK_VERIFYTRACK function (0x0008, 0x0065)
except that I/O is offset from the beginning of the physical drive instead
of from the unit number.
 
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.
