|
---|
| 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.
