|

4 | * We have create three types of pools:
|
---|
5 | * 1) MEMPOOL - standard pools
|
---|
6 | * 2) MALLOC_MEMPOOL - to be used by mem_malloc in mem.c
|
---|
7 | * 3) PBUF_MEMPOOL - a mempool of pbuf's, so include space for the pbuf struct
|
---|
8 | *
|
---|
9 | * If the include'r doesn't require any special treatment of each of the types
|
---|
10 | * above, then will declare #2 & #3 to be just standard mempools.
