Member Function Documentation

◆ parse()

virtual ssize_t libbgp::BgpMessage::parse	(	const uint8_t *	from,
		size_t	msg_sz
	)

pure virtual

Deserialize a BGP message body.

BgpMessage deserializer only deserialize message body. (i.e. message without BGP marker and message length field) To deserialize a BGP packet, use BgpPacket.

Parameters

from	Pointer to message body buffer.
msg_sz	Size of message.

Returns: ssize_t Bytes read.

Return values

-1	Deserialization error. Error may be logged.
>=0	Bytes read.

Exceptions

bad_parse	Internal deserialization error.
bad_type	The type of message/field member in buffer does not match the attribute type of container.

Implements libbgp::Serializable.

Implemented in libbgp::BgpUpdateMessage, libbgp::BgpNotificationMessage, libbgp::BgpOpenMessage, libbgp::BgpKeepaliveMessage, and libbgp::BgpBadMessage.

Referenced by BgpMessage().

◆ write()

virtual ssize_t libbgp::BgpMessage::write	(	uint8_t *	to,
		size_t	buf_sz
	)		const

pure virtual

Serialize a BGP message body.

BgpMessage serializer only serialize message body. (i.e. message without BGP marker and message length field) To serialize a BGP packet, use BgpPacket.
