The IOCTL_SCSISCAN_SET_TIMEOUT control code modifies the time-out value used by the kernel-mode still image driver for SCSI buses when it accesses a device.
The location containing a time-out value, in half seconds.
Input Buffer Length
Size of the input buffer
Set to NULL.
Output Buffer Length
Set to 0.
Irp->IoStatus.Status is set to STATUS_SUCCESS if the request is successful. Otherwise, Status to the appropriate error condition as a NTSTATUS code.
When the kernel-mode SCSI still image driver sends a SCSI command to a device, by default the driver waits 30 seconds before timing out the operation. You can change the time-out value for a device by calling the DeviceloControl function with the IOCTL_SCSISCAN_CMD control code. The specified time-out value stays in effect until the device is closed.
Time-out values are specified in half seconds. Thus a specified value of 100 causes the driver to wait 50 seconds before timing out the device.
