MEMPOOL_RESIZE(9) | Memory Management in Linux | MEMPOOL_RESIZE(9) |
NAME¶
mempool_resize - resize an existing memory poolSYNOPSIS¶
int
mempool_resize(mempool_t * pool,
int new_min_nr);
ARGUMENTS¶
poolpointer to the memory pool which was allocated via
mempool_create.
new_min_nr
the new minimum number of elements guaranteed to be
allocated for this pool.
DESCRIPTION¶
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.COPYRIGHT¶
