PROBLEM: documentation error in man page for ptsname(3)

[Charlie Gordon]

The prototype for ptsname_r is incorrect.  It reads:

char *ptsname_r(int fd, char *buf, size_t buflen);

The actual prototype for this function in glibc stdlib.h is

extern int ptsname_r (int __fd, char *__buf, size_t __buflen);

This is very confusing as the test for an error is exactly the opposite ;-)

The manual page is dated 2004-12-17, but seems current as part of release 
2.79.  The bug is present in the online version at 
http://www.kernel.org/doc/man-pages/online/pages/man3/ptsname.3.html .
