MirOS Manual: perror(3)

PERROR(3)                  BSD Programmer's Manual                   PERROR(3)

NAME

     perror - write error messages to standard error

SYNOPSIS

     #include <stdio.h>

     void
     perror(const char *string);

DESCRIPTION

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

     If the argument string is not the NULL pointer and is not zero length, it
     is prepended to the message string and separated from it by a colon and a
     space (': '). Otherwise, 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.

SEE ALSO

     intro(2), psignal(3), setlocale(3), strerror(3)

STANDARDS

     The perror() function conforms to ANSI X3.159-1989 ("ANSI C").
