NAME
       perror - Write a message explaining the current setting of errno

SYNOPSIS
       #include <stdio.h>

       void perror(
	       const char *string );

LIBRARY
       Standard C Library (libc)

STANDARDS
       Interfaces  documented on this reference page conform to industry stan‐
       dards as follows:

       perror():  ISO C, POSIX.1, XPG4, XPG4-UNIX

       Refer to the standards(5) reference page	 for  more  information	 about
       industry standards and associated tags.

PARAMETERS
       Points  to  a string containing the name of the program that caused the
       error.

DESCRIPTION
       The perror() function writes a message on  the  standard	 error	stream
       that  describes the current setting of the external variable errno. The
       error message includes the string pointed to by the  string  parameter,
       followed by a : (colon), a blank, the system message string, and a new‐
       line character. The string parameter string should point to the name of
       the program that caused the error.

       To get the system error message string for use by a program, as opposed
       to displaying it on standard error, use the  strerror()	function.  For
       more information, see strerror(3).
