81 * allocation and deallocation.
83 #ifndef SYS_LIGHTWEIGHT_PROT
84 #define SYS_LIGHTWEIGHT_PROT 1
88 * NO_SYS==1: Provides VERY minimal functionality. Otherwise,
89 * use lwIP facilities.
96 * MEMCPY: override this if you have a faster implementation at hand than the
97 * one included in your C library
100 #define MEMCPY(dst,src,len) memcpy(dst,src,len)
104 * SMEMCPY: override this with care! Some compilers (e.g. gcc) can inline a
105 * call to memcpy() if the length is known at compile time and is small.

193 * MEMP_USE_CUSTOM_POOLS==1: whether to include a user file lwippools.h
194 * that defines additional pools beyond the "standard" ones required
195 * by lwIP. If you set this to 1, you must have lwippools.h in your
196 * inlude path somewhere.

206 * If set to 1, mem_malloc will be protected by a semaphore and SYS_ARCH_PROTECT,
207 * while mem_free will only use SYS_ARCH_PROTECT. mem_malloc SYS_ARCH_UNPROTECTs
208 * with each loop so that mem_free can run.
210 * ATTENTION: As you can see from the above description, this leads to dis-/

386 * You may want to disable this if you do not trust LAN peers to have the
387 * correct addresses, or as a limited approach to attempt to handle

993 * to be sent into one single pbuf. This is for compatibility with DMA-enabled
994 * MACs that do not support scatter-gather.
995 * Beware that this might involve CPU-memcpy before transmitting that would not
996 * be needed without this flag! Use this only if you need to!
