int atexit( void (*func)() );
|
||
Registers the function pointed to by func
to be called on normal program termination (via std::exit() or returning from main()
). The functions will be called in reverse order they were registered, i.e. the function registered last will be executed first.
The same function may be registered more than once.
atexit
is thread-safe: calling the function from several threads does not induce a data race.
The implementation is guaranteed to support the registration of at least 32 functions. The exact limit is implementation-defined.
