-.SH DESCRIPTION
-The function
-.BR _exit ()
-terminates the calling process "immediately".
-Any open file descriptors
-belonging to the process are closed; any children of the process are
-inherited by process 1,
-.IR init ,
-and the process's parent is sent a
-.B SIGCHLD
-signal.
-.LP
-The value
-.I status
-is returned to the parent process as the process's exit status, and
-can be collected using one of the
-.BR wait (2)
-family of calls.
-.LP
-The function
-.BR _Exit ()
-is equivalent to
-.BR _exit ().
-.SH RETURN VALUE
-These functions do not return.
-.SH CONFORMING TO
-SVr4, POSIX.1-2001, 4.3BSD.
-The function
-.BR _Exit ()
-was introduced by C99.
-.SH NOTES
-For a discussion on the effects of an exit, the transmission of
-exit status, zombie processes, signals sent, and so on, see
-.BR exit (3).
-.LP
-The function
-.BR _exit ()
-is like
-.BR exit (3),
-but does not call any
-functions registered with
-.BR atexit (3)
-or
-.BR on_exit (3).
-Whether it flushes
-standard I/O buffers and removes temporary files created with
-.BR tmpfile (3)
-is implementation-dependent.
-On the other hand,
-.BR _exit ()
-does close open file descriptors, and this may cause an unknown delay,
-waiting for pending output to finish.
-If the delay is undesired,
-it may be useful to call functions like
-.BR tcflush (3)
-before calling
-.BR _exit ().
-Whether any pending I/O is canceled, and which pending I/O may be
-canceled upon
-.BR _exit (),
-is implementation-dependent.
-.SS C library/kernel ABI differences
-In glibc up to version 2.3, the
-.BR _exit ()
-wrapper function invoked the kernel system call of the same name.
-Since glibc 2.3, the wrapper function invokes
-.BR exit_group (2),
-in order to terminate all of the threads in a process.
