Actually, it would make more sense to make it use the library call,
getpseudotty(). This routine takes two char* args, and fills them
with the pathnames of the master and slave pty devices, and it returns
the file descriptor of the master side (opened for read and write),
which is pretty much what all that special code in emacs does.
It might be really nice to split off that code into a separate
file, getpty.c, with the appropriate #defines and #ifdefs to cause
it to call the system's routine, if it exists, and to use the current
code, otherwise.
BTW, all of this applies to Sequent's DYNIX 3.0 release -- their
previous version (2.1) uses the "normal" pty naming scheme, which
works with GNU Emacs just fine. If I ever find the time, I'll work
up an m-*.h and s-*.h setup which takes the v2.1-v3.0 changes into
account (such as MAIL_USE_FLOCK, etc.), but the current setup is
pretty close for v3.0, anyway.
