But the performance of it will suck badly.....

Something like:

char *
str_add(char *s, char *lim, const char *a)
{
	int c;

	do {
		if (s >= lim) {
			s = lim - 1;
			c = 0;
		} else
			c = *a++;
		*s++ = c;
	} while (c);

	return s;
}

So you can do:
	lim = buf + len;
	buf = str_add(buf, lim, "abc");
	buf = str_add(buf, lim, "123");
	...
might be safer.
