NAME¶

std::at_quick_exit - std::at_quick_exit

Synopsis¶

Defined in header <cstdlib>
int at_quick_exit( /*atexit-handler*/* func ) noexcept; (1) (since C++11)
int at_quick_exit( /*c-atexit-handler*/* func ) noexcept;
extern "C++" using /*atexit-handler*/ = void(); // exposition-only (2)
extern "C" using /*c-atexit-handler*/ = void(); // exposition-only

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.

Notes¶

The two overloads are distinct because the types of the parameter func are distinct
(language linkage is part of its type)
