Legacy Networking Libraries
This is an mbed 2 networking library. For mbed OS 5, lwip has been integrated with built-in networking interfaces. The networking libraries have been revised to better support additional network stacks and thread safety here.
This library is based on the code of lwIP v1.4.0

| mbed_official | 0:51ac1d130fd4 | 2 | * SETUP: Make sure we define everything we will need. |
| mbed_official | 0:51ac1d130fd4 | 3 | * |
| mbed_official | 0:51ac1d130fd4 | 4 | * We have create three types of pools: |
| mbed_official | 0:51ac1d130fd4 | 5 | * 1) MEMPOOL - standard pools |
| mbed_official | 0:51ac1d130fd4 | 6 | * 2) MALLOC_MEMPOOL - to be used by mem_malloc in mem.c |
| mbed_official | 0:51ac1d130fd4 | 7 | * 3) PBUF_MEMPOOL - a mempool of pbuf's, so include space for the pbuf struct |
| mbed_official | 0:51ac1d130fd4 | 8 | * |
| mbed_official | 0:51ac1d130fd4 | 9 | * If the include'r doesn't require any special treatment of each of the types |
| mbed_official | 0:51ac1d130fd4 | 10 | * above, then will declare #2 & #3 to be just standard mempools. |
