Detailed Description

Incoming message buffer. This structure keep all the information regarding the received message. This buffer lifetime is only very short, normally after the transaction has been called, this buffer will be deleted/recycled. So care must be taken when allocating storage from the pool of this buffer.

Forward declaration for receive data/buffer (sip_transport.h).

Field Documentation

pool

pj_pool_t* pjsip_rx_data::pool

Memory pool for this buffer.

transport

pjsip_transport* pjsip_rx_data::transport

The transport object which received this packet.

tp_data

void* pjsip_rx_data::tp_data

Other transport specific data to be attached to this buffer.

op_key

pjsip_rx_data_op_key pjsip_rx_data::op_key

Ioqueue key.

struct { ... } pjsip_rx_data::tp_info

tp_info is part of rdata that remains static for the duration of the buffer. It is initialized when the buffer was created by transport.

timestamp

pj_time_val pjsip_rx_data::timestamp

Time when the message was received.

packet

char pjsip_rx_data::packet[PJSIP_MAX_PKT_LEN]

Pointer to the original packet.

zero

pj_uint32_t pjsip_rx_data::zero

Zero termination for the packet.

len [1/2]

pj_ssize_t pjsip_rx_data::len

The length of the packet received.

src_addr

pj_sockaddr pjsip_rx_data::src_addr

The source address from which the packet was received.

src_addr_len

int pjsip_rx_data::src_addr_len

The length of the source address.

src_name

char pjsip_rx_data::src_name[PJ_INET6_ADDRSTRLEN]

The IP source address string (NULL terminated).

src_port

int pjsip_rx_data::src_port

The IP source port number.

struct { ... } pjsip_rx_data::pkt_info

pkt_info is initialized by transport when it receives an incoming packet.

msg_buf

char* pjsip_rx_data::msg_buf

Start of msg buffer.

len [2/2]

int pjsip_rx_data::len

Length fo message.

msg

pjsip_msg* pjsip_rx_data::msg

The parsed message, if any.

info

char* pjsip_rx_data::info

Short description about the message. Application should use pjsip_rx_data_get_info() instead.

cid

pjsip_cid_hdr* pjsip_rx_data::cid

The Call-ID header as found in the message.

from

pjsip_from_hdr* pjsip_rx_data::from

to

pjsip_to_hdr* pjsip_rx_data::to

The To header as found in the message.

via

pjsip_via_hdr* pjsip_rx_data::via

The topmost Via header as found in the message.

cseq

pjsip_cseq_hdr* pjsip_rx_data::cseq

The CSeq header as found in the message.

max_fwd

pjsip_max_fwd_hdr* pjsip_rx_data::max_fwd

route

pjsip_route_hdr* pjsip_rx_data::route

The first route header.

record_route

pjsip_rr_hdr* pjsip_rx_data::record_route

The first record-route header.

ctype

pjsip_ctype_hdr* pjsip_rx_data::ctype

Content-type header.

clen

pjsip_clen_hdr* pjsip_rx_data::clen

Content-length header.

"Require" header containing aggregates of all Require headers found in the message, or NULL.

supported

pjsip_supported_hdr* pjsip_rx_data::supported

"Supported" header containing aggregates of all Supported headers found in the message, or NULL.

parse_err

pjsip_parser_err_report pjsip_rx_data::parse_err

The list of error generated by the parser when parsing this message.

struct { ... } pjsip_rx_data::msg_info

msg_info is initialized by transport mgr (tpmgr) before this buffer is passed to endpoint.

mod_data

void* pjsip_rx_data::mod_data[PJSIP_MAX_MODULE]

Data attached by modules to this message.

struct { ... } pjsip_rx_data::endpt_info

endpt_info is initialized by endpoint after this buffer reaches endpoint.
