2014-03-17fix negated error codes from ptsname_rRich Felker-1/+1
the incorrect error codes also made their way into errno when __ptsname_r was called by plain ptsname, which reports errors via errno rather than a return value.
2012-06-20fix ptsname_r to conform to the upcoming posix requirementsRich Felker-3/+6
it should return the error code rather than 0/-1 and setting errno.
2011-04-13add ptsname_r (nonstandard) and split ptsname (standard) to separate fileRich Felker-11/+7
this eliminates the ugly static buffer in programs that use ptsname_r.
