EXIT(2)			    BSD System Calls Manual		       EXIT(2)

NAME
     _exit — terminate the calling process

SYNOPSIS
     #include <unistd.h>

     void
     _exit(int status);

DESCRIPTION
     The _exit() function terminates a process, with the following conse‐
     quences:

     ·	 All of the descriptors that were 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 has an outstanding wait
	 call or catches the SIGCHLD signal, it is notified of the calling
	 process's termination; the status is set as defined by wait(2).

     ·	 The parent process-ID of all of the calling process's existing child
	 processes are set to 1; the initialization process (see the DEFINI‐
	 TIONS section of intro(2)) inherits each of these processes.

     ·	 If the termination of the process causes any process group to become
	 orphaned (usually because the parents of all members of the group
	 have now exited; see “orphaned process group” in intro(2)), and if
	 any member of the orphaned group is stopped, the SIGHUP signal and
	 the SIGCONT signal are sent to all members of the newly-orphaned
	 process group.

     ·	 If the process is a controlling process (see intro(2)), the SIGHUP
	 signal is sent to the foreground process group of the controlling
	 terminal.  All current access to the controlling terminal is revoked.

     Most C programs call the library routine exit(3), which flushes buffers,
     closes streams, unlinks temporary files, etc., before calling _exit().

RETURN VALUE
     _exit() can never return.

SEE ALSO
     fork(2), sigaction(2), wait(2), exit(3)

STANDARDS
     The _exit function is defined by IEEE Std 1003.1-1988 (“POSIX.1”).
