ldns_status | ldns_wire2dname (ldns_rdf **dname, const uint8_t *wire, size_t max, size_t *pos) |
converts the data on the uint8_t bytearray (in wire format) to a DNS dname rdata field. | |
ldns_status | ldns_wire2rdf (ldns_rr *rr, const uint8_t *wire, size_t max, size_t *pos) |
converts the data on the uint8_t bytearray (in wire format) to a DNS rdata field, and adds it to the list of rdfs in the given rr. | |
ldns_status | ldns_wire2rr (ldns_rr **rr_p, const uint8_t *wire, size_t max, size_t *pos, ldns_pkt_section section) |
converts the data on the uint8_t bytearray (in wire format) to a DNS resource record. | |
ldns_status | ldns_buffer2pkt_wire (ldns_pkt **packet, ldns_buffer *buffer) |
converts the data on the uint8_t bytearray (in wire format) to a DNS packet. | |
ldns_status | ldns_wire2pkt (ldns_pkt **packet_p, const uint8_t *wire, size_t max) |
converts the data on the uint8_t bytearray (in wire format) to a DNS packet. |

) |
converts the data on the uint8_t bytearray (in wire format) to a DNS dname rdata field.
This function will initialize and allocate memory space for the dname structure. The length of the wiredata of this rdf is added to the *pos value.
[in] | dname | pointer to the structure to hold the rdata value |
[in] | wire | pointer to the buffer with the data |
[in] | max | the length of the data buffer (in bytes) |
[in] | pos | the position of the rdf in the buffer (ie. the number of bytes from the start of the buffer) |
