#define SECURE_STRNCAT	(	dst,
		src,
		size		)	do { strncat(dst, src, (size)-1); (dst)[(size)-1] = '\0'; } while (0)

Copy string src to dst. Copy at maximum size-1 characters and make sure that the string finish with a '\0'.

Workaround strncat security problem: if size is smaller than strlen(src), dst doesn't contains '\0'. This macro copy on maximum size-1 characters, and always write a '\0' on last position (dst[size-1]).
