memccpy - copy bytes in memory

Syntax	#include <string.h> void *memccpy(void *s1, const void *s2, int c, size_t n);
Description	memccpy() copies bytes from memory area s2 into s1 until either c is copied for the first time (where c is converted to an unsigned char), or n bytes have been copied. If the copy process affects objects which overlap, the behavior is undefined.
Return val.	Pointer to the byte after the copy of c in s1
		if successful..
	Null pointer	if memalloc() was unable to provide the memory, e.g. because the available memory space was insufficient for the request.
Notes	memccpy() does not check whether there will be an overflow in the memory area to which it copies.
