Libptytty 1.2

Libptytty is a small library that offers pseudo-TTY management in an OS-independent way.
It was created out of frustration over the many differences of PTY/TTY handling in different operating systems for use inside "rxvt-unicode".
It also offers session database support (utmp and optional wtmp/lastlog updates for login shells) and supports forking after startup and dropping privileges in the calling process. It offers C++ and C-only APIs.
SYNOPSIS:
cc ... -lptytty
#include
// C++
ptytty *pty = ptytty::create ();
if (!pty->get ())
// error allocating pty
if (we want utmp)
pty->login (process_pid, 0, "remote.host");
else if (we want utmp AND wtmp/lastlog)
pty->login (process_pid, 1, "remote.host");
// we are done with it
delete pty;
// C
PTYTTY pty = ptytty_create ();
if (!ptytty_get (pty))
// error allocating pty
if (we want utmp)
ptytty_login (pty, process_pid, 0, "remote.host");
else if (we want utmp AND wtmp/lastlog)
ptytty_login (pty, process_pid, 1, "remote.host");
// we are done with it
ptytty_delete (pty);
Enhancements:
- This release fixes libptytty on systems that dont support TIOCSCTTY (such as Cygwin and Solaris).
- It works around a bug in some openpty implementations by using ttyname again.
- A small memory leak when _getpty is being used was fixed.
