:mrdocs:

Reserve sufficient memory to satisfy allocation requests for at least the specified `numBytes` without replenishment (i.e., without dynamic allocation). If `numBytes` is 0, no memory is reserved. Note that, when the `numBytes` is distributed over multiple `allocate` requests ‐ due to alignment effects ‐ it is possible that not all `numBytes` of memory will be used for allocation before triggering dynamic allocation.
