NAME
        TD_REMCHANGEINT -- remove a disk change software interrupt handler.

   FUNCTION
        This command removes a disk change software interrupt added
        by a previous use of td_addchangeint.

   IO REQUEST INPUT
        The same IO request used for td_addchangeint.

        io_Device       preset by the call to opendevice()
        io_Unit         preset by the call to opendevice()
        io_Command      TD_REMCHANGEINT
        io_Flags        0
        io_Length       sizeof(struct Interrupt)
        io_Data         pointer to interrupt structure

   IO REQUEST RESULT
        io_Error - 0 for success, or an error code as defined in
                   <devices/trackdisk.h>

   BUGS
        This command did not function properly under versions of Kickstart
        earlier than V36. A valid workaround under these older versions of
        Kickstart is:

                Forbid();
                Remove(ioRequest);
                Permit();

        Do not use this workaround in versions of Kickstart >= V36, use
        TD_REMCHANGEINT instead (for future compatibility with V38+).
