perror(3c)

Standard C Library Functions                                        perror(3C)



NAME
       perror, errno - print system error messages

SYNOPSIS
       #include <stdio.h>

       void perror(const char *s)


       #include <errno.h>

DESCRIPTION
       The  perror()  function produces a message on the standard error output
       (file descriptor 2) describing the last error encountered by the thread
       during a call to a system or library function. The argument string s is
       printed, followed by a colon and a blank, followed by the message and a
       NEWLINE  character.  If s is a null pointer or points to a null string,
       the colon is not printed. The argument string should include  the  name
       of  the program that incurred the error. The error number is taken from
       the errno macro defined in <errno.h>. This per-thread value is set when
       errors  occur  but  not  cleared when non-erroneous calls are made. See
       Intro(2).

USAGE
       Messages printed from this function are in the native  language  speci‐
       fied by the LC_MESSAGES locale category. See setlocale(3C).
