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] Notes
The two overloads are distinct because the types of the parameter func are distinct (language linkage is part of its type)
