     perror - write error messages to standard error

SYNOPSIS    [Toc]    [Back]

     #include <stdio.h>

     void
     perror(const char *string);

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  are  the  same  as
those returned
     by strerror() with argument errno.
