     tsd - TELNET server protocol STREAMS device

DESCRIPTION    [Toc]    [Back]

     tsd is a STREAMS-based module that	provides Internet TELNET server
     protocol handling within the IRIX kernel.

     When the device special file /dev/tnclone is opened a stream is created
     and is attached to	a special terminal device. A program can call fstat(2)
     with the returned file descriptor to determine which device the stream
     has been connected	to. The	device behaves like a terminal with
     transparent TELNET	server protocol	processing.

     On	success, an open of tnclone returns a non-negative number.  On
     failure, it returns -1 and	errno is set to	one of the following values:

     ENXIO	  tsd devices are not configured into the kernel or all	are in
		  use.

     ENODEV	  Devices are not configured into the kernel, or device	file
		  does not exist, or device numbers are	incompatible.

     EBUSY	  Exclusive open failed	because	another	process	already	has
		  the device open.

CAVEATS    [Toc]    [Back]

     The tsd driver is intended	to be used only	by the telnetd(1M) program and
     the interface is likely to	change in future releases.
