std::at_quick_exit (3) Linux Manual Page

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)
