| u16_t mdns_compress_domain | ( | struct pbuf * | pbuf, | 
| u16_t * | offset, | ||
| struct mdns_domain * | domain | ||
| ) | 
Return bytes needed to write before jump for best result of compressing supplied domain against domain in outpacket starting at specified offset. If a match is found, offset is updated to where to jump to
| pbuf | Pointer to pbuf with the partially constructed DNS packet | 
| offset | Start position of a domain written earlier. If this location is suitable for compression, the pointer is updated to where in the domain to jump to. | 
| domain | The domain to write | 
| err_t mdns_domain_add_label | ( | struct mdns_domain * | domain, | 
| const char * | label, | ||
| u8_t | len | ||
| ) | 
Add a label part to a domain
| domain | The domain to add a label to | 
| label | The label to add, like <hostname>, 'local', 'com' or '' | 
| len | The length of the label | 
| int mdns_domain_eq | ( | struct mdns_domain * | a, | 
| struct mdns_domain * | b | ||
| ) | 
Return 1 if contents of domains match (case-insensitive)
| a | Domain name to compare 1 | 
| b | Domain name to compare 2 | 
| u16_t mdns_readname | ( | struct pbuf * | p, | 
| u16_t | offset, | ||
| struct mdns_domain * | domain | ||
| ) | 
Read possibly compressed domain name from packet buffer
| p | The packet | 
| offset | start position of domain name in packet | 
| domain | The domain name destination |
