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



     NAME
          exit - Flush buffers and terminate the process normally.

     SYNOPSIS
          void exit();
          int status;
          exit(status);

          where status is a return value.

     DESCRIPTION
          The exit function flushes the buffers associated with the
          stdio(3s) functions and terminates the process normally.
          The exit function also notifies the parent process if it is
          executing a wait(2) function.  The parent can use the low-
          order eight status bits; the status value must be between 0
          and 255.

     RETURNS
          If the function has a nonzero argument, it represents an
          error code to be passed back to the parent process.  If the
          current process was invoked by a C program using one of the
          exec functions, the return value is limited to 8 bits (0 -
          255).  A 0 value typically means no error occurred.

     SEE ALSO
          abort(3c), exec(2), wait(2), fork(2), vfork(2), wait3(2).

     EXAMPLE
          /* Program test for the exit() function */

          #include <stdio.h>

          int     err, atoi(), exit();
          main(argc, argv)
          int     argc;
          char    *argv[];
          {
              err = atoi(argv[1]);
              exit(err);
          }

          If you call the program test with an argument of 256, you
          receive the message

          *WARNING*
          Program 'exit'ed with a status of 0400
          WARNING: FROM PROGRAM
