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.
Parameters
func | - | pointer to a function to be called on quick program termination |
Return value
0
if the registration succeeds, nonzero value otherwise.
Exceptions
noexcept
specification: noexcept
