strerror(3C)               DG/UX 4.30                strerror(3C)



     NAME
          strerror - Return a string corresponding to an error code.

     SYNOPSIS
          char *strerror(), *message;
          int errno;
          message = strerror(errno);

          where   errno is the error code of the message string.

     DESCRIPTION
          The strerror function returns a pointer to a string
          corresponding to a given error code.  The message is the
          same text that perror(3c) would print (but without the
          leading colon and blank and without a trailing newline).

     RETURNS
          A pointer to an error message string, or NULL if an error
          occurred.

     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.
