TD_EJECT

eject (or load) the disk in the drive, if possible.

This command causes the drive to attempt to eject the disk in it, if any. Note that the current trackdisk.device does not implement this command, but it might in the future, and other trackdisk-compatible drivers may implement this command. Some devices may be able to load disks on command also.

io_Device

preset by the call to OpenDevice()

io_Unit

preset by the call to OpenDevice()

io_Command

TD_EJECT

io_Flags

0 or IOF_QUICK

io_Length

0 (load, if supported) or 1 (eject)

io_Error

0 for success, or an error code as defined in <devices/trackdisk.h>

The pre-V40 autodoc didn't mention io_Length. Because of this, for devices that can never support load, a driver might want to eject if io_Length is 0.
