exit -- perform normal program termination
Standard C Library (libc, -lc)
exit() terminates a process. The status values EXIT_SUCCESS and
EXIT_FAILURE can be used to indicate successful and unsuccessful termina-
Before termination it performs the following functions in the order
1. Call the functions registered with the atexit(3) function, in
the reverse order of their registration.
2. Flush all open output streams.
3. Close all open streams.
4. Unlink all files created with the tmpfile(3) function.
Following this, exit() calls _exit(2). Note that typically _exit(2) only
passes the lower 8 bits of status on to the parent, thus negative values
have less meaning.
The exit() function never returns.
_exit(2), atexit(3), intro(3), tmpfile(3)
The exit() function conforms to ANSI X3.159-1989 (``ANSI C89'').
