add_memleak_data()

void mem_guarded::internal::add_memleak_data

(

std::any

data

)

Store a std::any into a static opaque storage vector. The only purpose of this call is to control the lifetime of the given data, there is no way to access it from here afterwards. User code is expected to keep its own reference to the data contained in the std::any as long as it needs it.

Typically, this any should contain a shared_ptr to the actual data, to ensure that the data itself is not duplicated, and that the static storage does become an owner of it.

That way, the memleak data does not get destructed before the static storage is. Since this storage is created before the memleak detection data (see the implementation of MEM_init_memleak_detection), it is guaranteed to happen after the execution and destruction of the memleak detector.
