[comp.unix.questions] /dev/ptmx -- what is it?

kmeek@cti1.UUCP (Kevin Meek) (07/28/90)

I am trying to compile Xwindows client applications my AT&T 3B2/600G.
We are running System V 3.2.2.  

The problem I am having is that /dev/ptmx does not exist.  (I think 
this is the psuedo terminal master clone device)  The xdaemon is
trying to clone this device but it doesn't exist.

How do I create /dev/ptmx?  

I have found /dev/ptmx referenced in a book that says it is
part of System V 3.2.  Was this changed or do I just need to 
reconfigure my system to have it created.

Any suggestions would be welcomed.

P.S.  Anyone ever seen any documentation that talks about functions
      grantpt(), unlockpt(), ptsname() in libpt.a ??

Yes, they're documented in the System V Release 4.0 Programmer's
Reference Manual; they probably work similarly in S5R3.2.
