NAME
       _exit - terminate a process

SYNOPSIS
       _exit(status)
       int status;

DESCRIPTION
       __e_x_i_t terminates a process with the following consequences:

       All  of  the  descriptors open in the calling process are closed.  This
       may entail delays, for example, waiting for output to drain; a  process
       in this state may not be killed, as it is already dying.

       If  the parent process of the calling process is executing a _w_a_i_t or is
       interested in the SIGCHLD signal, then it is notified  of  the  calling
       process’s  termination  and the low-order eight bits of _s_t_a_t_u_s are made
       available to it; see _w_a_i_t(2).

       The parent process ID of all of the calling  process’s  existing  child
       processes  are  also set to 1.  This means that the initialization pro‐
       cess (see _i_n_t_r_o(2)) inherits each of  these  processes  as  well.   Any
       stopped children are restarted with a hangup signal (SIGHUP).

       Most  C  programs  call  the  library  routine  _e_x_i_t(3), which performs
       cleanup actions in the standard I/O library before calling __e_x_i_t.

RETURN VALUE
       This call never returns.
