NAME

       perror -  Writes a message explaining the current setting of errno

LIBRARY

       Standard C Library (libc.a, libc.so)

SYNOPSIS

       #include <stdio.h>

       void perror(
	       const char *string);

STANDARDS

       Interfaces documented on this reference page conform to industry standards 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
       newline 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).
