Detailed Description

Macro Definition Documentation

MEMCPY

#define MEMCPY	(		dst,
			src,
			len
	)		memcpy(dst,src,len)

MEMCPY: override this if you have a faster implementation at hand than the one included in your C library

MEMMOVE

#define MEMMOVE	(		dst,
			src,
			len
	)		memmove(dst,src,len)

MEMMOVE: override this if you have a faster implementation at hand than the one included in your C library. lwIP currently uses MEMMOVE only when IPv6 fragmentation support is enabled.

SMEMCPY

#define SMEMCPY	(		dst,
			src,
			len
	)		memcpy(dst,src,len)

SMEMCPY: override this with care! Some compilers (e.g. gcc) can inline a call to memcpy() if the length is known at compile time and is small.
