Method Protocols.DNS.protocol()->decode_entries()

Method decode_entries

array decode_entries(string s, int num, array(int) next)

Description

Decode a set of entries from an answer.

Parameter s

Encoded entries.

Parameter num

Number of entires in s .

Parameter next

Array with a single element containing the start position in s on entry and the continuation position on return.

Returns

Returns an array of mappings describing the decoded entires:

Array mapping 0.. Mapping describing a single entry: "name" : string Name the entry concerns. "type" : EntryType Type of entry. "cl" : ResourceClass Resource class. Typically C_IN . "ttl" : int Time to live for the entry in seconds. "len" : int Length in bytes of the encoded data section. Depending on the type of entry the mapping may contain different additional fields: T_CNAME "cname" : string T_PTR "ptr" : string T_NS "ns" : string T_MX "preference" : int "mx" : string T_HINFO "cpu" : string "os" : string T_SRV RFC 2052 and RFC 2782. "priority" : int "weight" : int "port" : int "target" : string "service" : string "proto" : string "name" : string T_A "a" : string IPv4-address in dotted-decimal format. T_AAAA "aaaa" : string IPv6-address in colon-separated hexadecimal format. T_LOC "version" : int Version, currently only version 0 (zero) is supported. "size" : int   "h_perc" : int   "v_perc" : int   "lat" : int   "long" : int   "alt" : int   T_SOA "mname" : string   "rname" : string   "serial" : int   "refresh" : int   "retry" : int   "expire" : int   "minimum" : int Note: For historical reasons this entry is named "minimum", but it contains the TTL for negative answers (RFC 2308). T_NAPTR "order" : int "preference" : int "flags" : string "service" : string "regexp" : string "replacement" : string T_TXT "txt" : string Note: For historical reasons, when receiving decoded DNS entries from a client, this will be the first string in the TXT record only. "txta" : string When receiving decoded DNS data from a client, txta is the array of all strings in the record. When sending multiple strings in a TXT record in a server, please supply an array as "txt" containing the strings, txta will be ignored. T_SPF "spf" : string
