NAME
       ptsname() - get the pathname of a slave pty (pseudo-terminal)

SYNOPSIS
   Obsolescent Interfaces
   Remarks
       supports	 STREAMS pty (see ptm(7) and pts(7)), and non-STREAMS pty (see
       pty(7)) which have different device naming  conventions.	  Notice  that
       the  STREAMS  pty, being an optional feature, is supported only when it
       is installed on the system.

       is useful only on systems that follow the insf(1M)  naming  conventions
       for pty (STREAMS and non-STREAMS).

DESCRIPTION
       The  passed parameter, fildes, is a file descriptor of an opened master
       pty.  generates the name of the slave pty corresponding to this	master
       pty.  This means that their minor numbers will be identical.

   Obsolescent Interfaces
       gets the pathname of a slave pty (pseudo-terminal).

RETURN VALUE
       Upon  successful	 completion, returns a string containing the full path
       name of a slave pty.  Otherwise,	 a  NULL  pointer  is  returned.   The
       return  value  is pointed to static data area which is overwritten with
       each call to so it should be copied if it is to be saved.

ERRORS
       fails and returns a NULL pointer under the following conditions:

	      ·	 File descriptor does not refer to an open master pty.

	      ·	 Request falls outside pty name-space.

	      ·	 Pty device naming conventions have not been followed.

	      ·	 failed to find a match.

WARNINGS
       is obsolescent interface supported only for compatibility with existing
       DCE applications.  New multi-threaded applications should use

EXAMPLES
       The  following  example shows how is typically used for non-STREAMS pty
       to obtain the pathname of the slave pty corresponding to a  master  pty
       obtained through a pty clone open.

       pathname of the STREAMS slave pty corresponding	to  a  STREAMS	master
       pty.
