strerror(3C)                     DG/UX 5.4.2                    strerror(3C)


NAME
       strerror - get error message string

SYNOPSIS
       #include <string.h>

       char *strerror (int errnum);

DESCRIPTION
       strerror maps the error number in errnum to an error message string,
       and returns a pointer to that string.  strerror uses the same set of
       error messages as perror.  The returned string should not be
       overwritten.

SEE ALSO
       perror(3C).

EXAMPLE
       The following program prints an error message corresponding to the
       generic UNIX I/O message.

       /* Program test for the strerror() function */

       #include <errno.h>
       #include <stdio.h>

       char *strerror();

       main() {
           printf("Error message is: %s\n", strerror(EIO));
           return 0;
       }

       A call to this program generates the output

       Error message is: Error EIO(5) -- Error in input/ouput.
