Member Function Documentation

virtual void RTCP_Packet::build_packet ( void )

protectedpure virtual

Used to create the byte representation of the RTCP packet. Defined in child class.

void RTCP_Packet::get_packet_data	(	char **	buffer,
		ACE_UINT16 &	length
	)

Returns a pointer to a local buffer containing the packet.

int RTCP_Packet::is_valid ( char is_first )

Checks the validity of an RTCP packet. RTCP packets can be sent together in a compound packet and is_first indicates the first packet in a compound packet

virtual unsigned int RTCP_Packet::packet_size ( void )

pure virtual

Returns the size of the packet. Defined in child class.

Implemented in RTCP_SR_Packet, RTCP_SDES_Packet, RTCP_RR_Packet, and RTCP_BYE_Packet.
