Defined in header <cstdlib>
extern "C"   int at_quick_exit( void (*func)() ); extern "C++" int at_quick_exit( void (*func)() );		(since C++11)

Registers the function pointed to by func to be called on quick program termination (via std::quick_exit).

Calling the function from several threads does not induce a data race. The implementation shall support the registration of at least 32 functions.

The registered functions will not be called on normal program termination. If a function need to be called in that case, std::atexit must be used.

Parameters

func

-

pointer to a function to be called on quick program termination

Return value

​0​ if the registration succeeds, nonzero value otherwise.

Exceptions

noexcept specification:  

noexcept
