* @file
* Dynamic memory manager
*
* This is a lightweight replacement for the standard C library malloc().
*
* If you want to use the standard C library malloc() instead, define
* MEM_LIBC_MALLOC to 1 in your lwipopts.h
*
* To let mem_malloc() use pools (prevents fragmentation and is much faster than
* a heap but might waste some memory), define MEM_USE_POOLS to 1, define
* MEM_USE_CUSTOM_POOLS to 1 and create a file "lwippools.h" that includes a list
* of pools like the this (more pools can be added between _START and _END):
*
* /* Define three pools with sizes 256, 512, and 1512 bytes
* LWIP_MALLOC_MEMPOOL_START
* LWIP_MALLOC_MEMPOOL(20, 256)
* LWIP_MALLOC_MEMPOOL(10, 512)
* LWIP_MALLOC_MEMPOOL(5, 1512)
* LWIP_MALLOC_MEMPOOL_END
