<p><code>mi_</code> prefixed implementations of various allocation functions that use C++ semantics on out-of-memory, generally calling <code>std::get_new_handler</code> and raising a <code>std::bad_alloc</code> exception on failure. </p>
<p>Note: use the <code>mimalloc-new-delete.h</code> header to override the <em>new</em> and <em>delete</em> operators globally. The wrappers here are mostly for convience for library writers that need to interface with mimalloc from C++. </p>
