struct mpool

Memory pool: a threadsafe malloc()/free() over a set of memory chunks.

Memory chunks must be fixed size.

Public Members

dptr_t *elements: The chunks of managed memory.

struct llist_node *nodes: Space for the llist nodes for both the free and allocated lists.

struct llist free: List of free chunks of memory.

struct llist alloc: List of free chunks of memory.

int *refs: Reference counting. Same length as max # elements.

size_t elt_size: Size of elements in the pool in bytes.

size_t max_elts: Max # of elements in the pool. Must be > 0.

struct csem slots_avail: Used to wait for a chunk to become free in mpool_req().

struct mutex mutex: Lock around most operations for concurrency safety.

uint32_t flags

Run time configuration flags. Valid flags are:

All other flags are ignored.
