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 functions.
 

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.
