I think this is standardized in Unix98. And they choose the Solaris way
(/dev/ptmx, and /dev/pts/...) But we have to support all earlier OS's too.
(as I see there are two completely different approaches: BSD and Solaris)
* BSD has a couple of /dev/pty* and corressponding /dev/tty* devices, the
differences between vendors is the possible characters after pty* (e.g.
under Linux (debian) first character is between 'p' .. 'q', and the
second is between '0' - 'f') We'll need a configure check to find
out which devices are available. (Maybe search for /dev/pty*, and define
the ranges of the two characters independently)
* The solaris way (I think this comes from SysV) is to open /dev/ptmx,
call grantpt() on the opened fd to set permissions, and finally call
ptsname() to get the name of the to-be-opened slave pty. BTW: Solaris
seems to support the BSD way too. (e.g. /dev/pty* exists, just as
/dev/ptmx is)

I'll check this one.

seems to be an overkill to download the whole source tree.

already checked this one.
