USHORT DosDevIOCtl(pbBlock, pbCommand, 0x0063, 0x0009, hDevice)
PBYTE pbBlock;      /* pointer to structure for device parameters */
PBYTE pbCommand;    /* pointer to variable with command           */

The PDSK_GETPHYSDEVICEPARAMS function retrieves the device parameters for a
physical device. The retrieved parameters apply to the entire physical
disk.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
pbBlock    Points to the DEVICEPARAMETERBLOCK structure that receives the
           device parameters.
 
pbCommand  Points to the variable that contains a reserved value. The value
           must be zero.
 
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.
