EXIT(3) 			   BSD Library Functions Manual 			  EXIT(3)

NAME
     exit -- perform normal program termination

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <stdlib.h>

     void
     exit(int status);

DESCRIPTION
     exit() terminates a process.  The status values EXIT_SUCCESS and EXIT_FAILURE can be used to
     indicate successful and unsuccessful termination, respectively.

     Before termination it performs the following functions in the order listed:

	   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).

RESTRICTIONS
     Standard C guarantees only that the values zero, EXIT_SUCCESS, and EXIT_FAILURE produce
     meaningful results.  POSIX extends this to guarantee that the least significant 8 bits of
     status are preserved and returned to the parent via wait(2).  Values outside the supported
     range 0-255 are bitwise-truncated; therefore, negative values should not be used.

RETURN VALUES
     The exit() function never returns.

SEE ALSO
     _exit(2), atexit(3), intro(3), tmpfile(3)

STANDARDS
     The exit() function conforms to ANSI X3.159-1989 (``ANSI C89'').
