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 variable errno, which is set when errors occur but not
cleared when non-erroneous calls are made.
