mempool_resize — resize an existing memory pool


int mempool_resize (mempool_t * pool,
 int new_min_nr);


mempool_t * pool

pointer to the memory pool which was allocated via mempool_create.

int new_min_nr

the new minimum number of elements guaranteed to be allocated for this pool.


This function shrinks/grows the pool. In the case of growing, it cannot be guaranteed that the pool will be grown to the new size immediately, but new mempool_free calls will refill it. This function may sleep.

Note, the caller must guarantee that no mempool_destroy is called while this function is running. mempool_alloc & mempool_free might be called (eg. from IRQ contexts) while this function executes.
