ptsname: reject invalid file descriptors POSIX left errno undefined on ptsname() failure, although there has at least been an effort to specify reasonable values to use: http://www.austingroupbugs.net/view.php?id=503 However, our tests for ptsname and ptsname_r already require errno to be set to useful values (as in glibc), so it is worth replacing ptsname on FreeBSD 8.2 in order to get better QoI and pass the test. * m4/ptsname.m4 (gl_FUNC_PTSNAME): Probe for FreeBSD bug. * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Add new witness. * modules/stdlib (Makefile.am): Replace witness. * lib/stdlib.in.h (ptsname): Allow for replacement. * modules/ptsname (configure.ac): Trigger replacement. * doc/posix-functions/ptsname.texi (ptsname): Document this.
