EXIT(2)                                                   EXIT(2)

     NAME
          exit - terminate process

     SYNOPSIS
          exit(status)
          int status;

          _exit(status)
          int status;

     DESCRIPTION
          Exit is the normal means of terminating a process.  Exit
          closes all the process's files and notifies the parent pro-
          cess if it is executing a wait. The low-order 8 bits of
          status are available to the parent process.

          This call can never return.

          The C function exit may cause cleanup actions before the
          final `sys exit'.  The function _exit circumvents all
          cleanup, and should be used to terminate a child process
          after a fork(2) to avoid flushing buffered output twice.
