Detailed Description

The BgpNotificationMessage object.

This is deserializer/serializer for BGP notification message body. If you want to deserializer/serializer a full BGP message. Take a look at BgpPacket class.

Member Function Documentation

doPrint()

ssize_t libbgp::BgpNotificationMessage::doPrint ( size_t  indent, uint8_t **  to, size_t *  buf_sz  ) const

virtual

Print implementation.

Parameters

indent	indent level.
to	The pointer to the pointer to the string buffer.
buf_sz	The pointer to the counter of avaliable buffer space.

Returns

ssize_t ssize_t Bytes written.

Return values

-1	Failed to print.
>=	0 Bytes written.

Implements libbgp::Serializable.

Definition at line 83 of file bgp-notification-message.cc.

References libbgp::Serializable::_print(), and libbgp::bgp_error_code_str.

parse()

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

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::BgpMessage.

write()

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

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.

Parameters

to	Pointer to destination buffer.
buf_sz	Max write size.

Returns

ssize_t Bytes written.

Return values

-1	Serialization error. Error may be logged.
>=0	Bytes written.

Implements libbgp::BgpMessage.
