std::at_quick_exit
Defined in header <cstdlib>

int at_quick_exit( /*atexit-handler*/* func ) noexcept; int at_quick_exit( /*c-atexit-handler*/* func ) noexcept; |
(1) | (since C++11) |
extern "C++" using /*atexit-handler*/ = void(); // exposition-only 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)
