:relfileprefix: ../../../
:mrdocs:

Reserve memory from this pool to satisfy memory requests for at least the specified `numObjects` before the pool replenishes. The behavior is undefined unless `0 <= numObjects`. Return 0 on success and the number of objects that could not be reserved otherwise. Note that this method fails if the number of memory blocks already allocated plus `numObjects` exceeds `poolSize()`.
