Detailed Description

MDNS responder private definitions.

Definition in file mdns_priv.h.

Function Documentation

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

Parameters:

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

Returns:: Number of bytes to write of the new domain before writing a jump to the offset. If compression can not be done against this previous domain name, the full new domain length is returned.

Add a label part to a domain.

Parameters:

domain	The domain to add a label to
label	The label to add, like <hostname>, 'local', 'com' or ''
len	The length of the label

Definition at line 272 of file lwip_mdns.c.

Return 1 if contents of domains match (case-insensitive)

Parameters:

a	Domain name to compare 1
b	Domain name to compare 2

Definition at line 404 of file lwip_mdns.c.

Read possibly compressed domain name from packet buffer.

Parameters:

p	The packet
offset	start position of domain name in packet
domain	The domain name destination

Returns:: The new offset after the domain, or MDNS_READNAME_ERROR if reading failed
