It's a private function - don't use it.

However, it's not overly complex - here's how it ends up

        #define NS_GET16(s, cp) do { \
        	register u_char *t_cp = (u_char *)(cp); \
        	(s) = ((u_int16_t)t_cp[0] << 8) \
        	    | ((u_int16_t)t_cp[1]) \
        	    ; \
        	(cp) += NS_INT16SZ; \
        } while (0) 


u_int
ns_get16(const u_char *src) {
	u_int dst;
 
	NS_GET16(dst, src);
	return (dst);
}
libresolv_hidden_def (ns_get16)

u_int16_t _getshort(const u_char *src) { return (ns_get16(src)); }

Thanks
