DESCRIPTION    [Toc]    [Back]

     The perror() function looks up the language-dependent error message
     string affiliated with an error number and writes it, followed by a newline,
 to the standard error stream.

     If the argument string is non-NULL it is prepended to the message string
     and separated from it by a colon and a space (`: ').  If string is NULL
     only the error message string is printed.

     The contents of the error message string is the same as those returned by
     strerror() with argument errno.
