EXIT(3C) Standard C Library Functions EXIT(3C)
NAME
exit, _exithandle - terminate process
SYNOPSIS
#include <stdlib.h>
void exit(
int status);
void _exithandle(
void);
DESCRIPTION
The
exit() function terminates a process by calling first
_exithandle() and then
_exit() (see
exit(2)).
The
_exithandle() function calls any functions registered through
the
atexit(3C) function in the reverse order of their registration.
This action includes executing all finalization code from the
.fini sections of all objects that are part of the process.
The
_exithandle() function is intended for use
only with
_exit(), and
allows for specialized processing such as
dldump(3C) to be performed.
Normal process execution should not be continued after a call to
_exithandle() has occurred, as internal data structures may have been
torn down due to
atexit() or
.fini processing.
The symbols
EXIT_SUCCESS and
EXIT_FAILURE are defined in the header
<
stdlib.h> and may be used as the value of
status to indicate
successful or unsuccessful termination, respectively.
