#include <stdlib.h> int
atexit (void (*function)(void));
DESCRIPTION
The
atexit ();
function
registers the given
Fa function
to be called at program exit, whether via
exit(3)
or via return from the program's
main (.);
Functions so registered are called in reverse order;
no arguments are passed.
These functions must not call
exit (;);
if it should be necessary to terminate the process while in such a
function, the
_exit2
function should be used.
(Alternatively, the function may cause abnormal
process termination, for example by calling
abort(3).)
At least 32 functions can always be registered,
and more are allowed as long as sufficient memory can be allocated.
RETURN VALUES
Rv -std atexit
ERRORS
Bq Er ENOMEM
