CHAPTER 3
The PC Interface Driver
42 Control and Status Calls
rsDisableVideo 3
You can use the rsDisableVideo control call to disable the VGA display output when
the Macintosh video output is connected to the video adapter cable. If the Macintosh
video is not connected, this call does nothing.
Parameter block
→ ioCompletion long Pointer to the completion routine
← ioResult word
→ ioRefNum word
→ csCode word Equals rsDisableVideo
rsMountDisks 3
You can use the rsMountDisks call to enable the mounting and unmounting of PC
disks. After the call has been made, the PC Interface driver monitors all disk-insertion
events, looking for possible PC formatted disks. If the inserted disk is not a Macintosh
formatted disk, it is considered a PC disk and is made available to the PC if the PC is
active. The mounting and unmounting of the PC disks happens automatically; the
rsMountDisks call merely enables the process.
Parameter block
→ ioCompletion long Pointer to the completion routine
← ioResult word
→ ioRefNum word
→ csCode word Equals rsMountDisks
rsDontMountDisks 3
You can use the rsDontMountDisks control call to stop the PC Interface driver from
monitoring disk-insertion events. If the PC Interface driver has already mounted a PC
disk before you make this call, the PC disk remains in the drive and available to the PC.
