       NAME
             perror - print system error messages

       SYNOPSIS
             #include <stdio.h>
             void perror (const char *s);

       DESCRIPTION
             perror produces a message on the standard error output (file
             descriptor 2), describing the last error encountered during a
             call to a system or library function.  The argument string s
             is printed first, then a colon and a blank, then the message
             and a newline.  (However, if s is a null pointer or points to
             a null string, the colon is not printed.)  To be of most use,
             the argument string should include the name of the program
             that incurred the error.  The error number is taken from the
             external variable errno, which is set when errors occur but
             not cleared when non-erroneous calls are made.

       NOTICES
             perror uses the UNIX System V Message Handling Facility.  The
             message is retrieved from the locale-specific version of the
             system catalog uxsyserr.
