Functions ¶

func Name ¶

func Name(msgBuf []byte, off int) int

Name jumps the name that should start msgBuf[off].

func Question ¶

func Question(msgBuf []byte, off int) int

Question jumps the question section that should start at msgBuf[off].

func RR ¶

func RR(msgBuf []byte, off int) int

RR jumps the RR that starts at msgBuf[off].

func To ¶

func To(i int, msgBuf []byte) int

To jumps to the start of the i-th RR in the message, that starts at msgBuf[0]. This counts from 0 which returns the RR *after* a possible question section. When we jump over the entire message, 0 is returned. The supported number of "RR"s in the question section is zero or one. The zero check is done by checking the Qdcount *in the buffer* as there is no other way of doing so.
