EXIT(3) FreeBSD 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.
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.
Passing arbitrary values back to the environment as status is considered
bad style; you should use the values EXIT_SUCCESS and EXIT_FAILURE. If
portability is not a concern, you may use the values described in
sysexits(3).
RETURN VALUES
The exit() function never returns.
SEE ALSO
_exit(2), atexit(3), intro(3), sysexits(3), tmpfile(3)
STANDARDS
The exit() function conforms to ISO/IEC 9899:1990 (``ISO C89'').
