This function is a wrapper function for ldns_get_rr_list_name_by_addr and ldns_get_rr_list_addr_by_name.
It's name is from the getaddrinfo() library call. It tries to mimic that call, but without the lowlevel stuff.
| [in] | res | The resolver. If this value is NULL then a resolver will be created by ldns_getaddrinfo. |
| [in] | node | the name or ip address to look up |
| [in] | c | the class to look in |
| [out] | list | put the found RR's in this list |
