Summary

Declaration

class CnameRecord : public ResourceRecord { public: static constexpr uint16_t kType = kTypeCname; void Init(uint16_t aClass = kClassInternet) { ResourceRecord::Init(kTypeCname, aClass); } Error ReadCanonicalName(const Message &aMessage, uint16_t &aOffset, char *aNameBuffer, uint16_t aNameBufferSize) const { return ResourceRecord::ReadName(aMessage, aOffset, aOffset - sizeof(CnameRecord), aNameBuffer, aNameBufferSize, true); } };

Fields

Field

ot::Dns::CnameRecord::kType

Methods

Init()

Initializes the CNAME Resource Record by setting its type and class. Other record fields (TTL, length) remain unchanged/uninitialized.

ReadCanonicalName() const

Parses and reads the CNAME alias name from a message. Also verifies that the CNAME record is well-formed (e.g., the record data length `GetLength()` matches the CNAME encoded name).
