Update.
1999-06-28 Andreas Jaeger <aj@arthur.rhein-neckar.de> * inet/rcmd.c (__icheckhost): Test for gethostbyname_r result correctly. 1999-06-25 Andreas Jaeger <aj@arthur.rhein-neckar.de> * manual/arith.texi (System V Number Conversion): Fix the description which confused pointer and value to pointer. Reported by Andries.Brouwer@cwi.nl. 1999-06-28 Andreas Jaeger <aj@arthur.rhein-neckar.de> * pwd/getpw.c (__getpw): Check for NULL result pointer. 1999-06-29 Andreas Jaeger <aj@arthur.rhein-neckar.de> * manual/users.texi (Lookup User): Document POSIX return semantics for getpwuid_r and getgrgid_r. * manual/socket.texi (Host Names): Document that the result pointer is null in case of error or host not found and fix a typo. Give a small example.
