atexit - register a function to run at process termination
Návod, kniha: POSIX Programmer's Manual
#include <stdlib.h>
int atexit(void (*
func)(void));
The
atexit() function shall register the function pointed to by
func, to be called without arguments at normal program termination. At
normal program termination, all functions registered by the
atexit()
function shall be called, in the reverse order of their registration, except
that a function is called after any previously registered functions that had
already been called at the time it was registered. Normal termination occurs
either by a call to
exit() or a return from
main().
At least 32 functions can be registered with
atexit().
After a successful call to any of the
exec functions, any functions
previously registered by
atexit() shall no longer be registered.
Upon successful completion,
atexit() shall return 0; otherwise, it shall
return a non-zero value.
No errors are defined.
The following sections are informative.
None.
The functions registered by a call to
atexit() must return to ensure that
all registered functions are called.
The application should call
sysconf() to obtain the value of
{ATEXIT_MAX}, the number of functions that can be registered. There is no way
for an application to tell how many functions have already been registered
with
atexit().
None.
None.
