# std::at_quick_exit

From cppreference.com
< cpp‎ | utility‎ | program

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.

### [edit] Parameters

func | - | pointer to a function to be called on quick program termination

### [edit] Return value

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

### [edit] Exceptions

`noexcept` specification:
noexcept
