NAME¶
mempool_create - create a memory pool
SYNOPSIS¶
mempool_t * mempool_create(int min_nr, mempool_alloc_t * alloc_fn, mempool_free_t * free_fn, void * pool_data);
ARGUMENTS¶
min_nr
the minimum number of elements guaranteed to be allocated
for this pool.
alloc_fn
user-defined element-allocation function.
free_fn
user-defined element-freeing function.
pool_data
optional private data available to the user-defined

DESCRIPTION¶
this function creates and allocates a guaranteed size, preallocated memory pool. The pool can be used from the mempool_alloc and mempool_free functions. This function might sleep. Both the alloc_fn and the free_fn functions might sleep - as long as the mempool_alloc function is not called from IRQ contexts.
