std::at_quick_exit: std::at_quick_exit
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)
