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.
