NAME
perror - print a system error message
SYNOPSIS
#include <stdio.h>
void perror(const char *s);
DESCRIPTION
perror produces a message on the standard error output,
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 new-line. 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 vari-
able errno, which is set when errors occur but not cleared
when non-erroneous calls are made.
