// FORMAT
|
|
//
|
|
// The dns package implements String() for all RR types, but sometimes you will
|
|
// need more flexibility. The functions Printf, Sprintf, etc. implemented formatted I/O
|
|
// for the RR type.
|
|
//
|
|
// Printing
|
|
//
|
|
// The verbs:
|
|
//
|
|
// Generic part of RRs:
|
|
//
|
|
// %N the owner name of the RR
|
|
// %C the class: IN, CH, CLASS15, etc.
|
|
// %D the TTL in seconds
|
|
// %Y the type: MX, A, etc.
|
|
//
|
|
// The rdata of each RR differs, we allow each field to be printed as a string.
|
|
//
|
|
// Rdata: (TODO)
|
|
//
|
|
// %0 the first rdata field
|
|
// %1 the second rdata field
|
|
// %2 the third rdata field
|
|
// .. ...
|
|
// %9 the nineth rdata field
|
|
// %R all rdata fields
