ptsname - GNU Gnulib

Gnulib module: ptsname

Portability problems fixed by Gnulib:

This function is missing on some platforms: Mac OS X 10.3, OpenBSD 3.8, Minix 3.1.8, mingw, MSVC 9, BeOS.
This function fails to set errno on failure on some platforms: FreeBSD 8.2.

Portability problems not fixed by Gnulib:

This function is not declared on some platforms: IRIX 5.3.
On Solaris 11 2010-11, this function fails on all BSD-style /dev/pty* device files.
This function is not thread-safe on some platforms: Cygwin 1.7.9. Likewise, the gnulib replacement is not thread-safe.

Note that the Gnulib module ptsname_r is a version of this function that is more likely to be thread-safe.
