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 |
void mdns_resp_register_name_result_cb | ( | mdns_name_result_cb_t | cb | ) |
Register a callback function that is called if probing is completed successfully or with a conflict.
