c_profile Struct Reference

The ROHC compression profile. More...

#include <rohc_comp.h>

List of all members.

Public Attributes
unsigned short	protocol
	The IP protocol ID used to find out which profile is able to compress an IP packet.
int *	ports
	The UDP ports associated with this profile Only used with UDP as transport protocol. The pointer can be NULL if no port is specified. If defined, the list must be terminated by 0. ex: { 5000, 5001, 0 }.
unsigned short	id
	The profile ID as reserved by IANA.
char *	version
	A string that describes the version of the implementation.
char *	description
	A string that describes the implementation (authors...)
int(*	create )(struct c_context *context, const struct ip_packet packet)
	The handler used to create the profile-specific part of the compression context.
void(*	destroy )(struct c_context *context)
	The handler used to destroy the profile-specific part of the compression context.
int(*	check_context )(struct c_context *context, struct ip_packet packet)
	The handler used to check whether an uncompressed IP packet belongs to a context or not.
int(*	encode )(struct c_context *context, const struct ip_packet packet, int packet_size, unsigned char *dest, int dest_size, int *payload_offset)
	The handler used to encode uncompressed IP packets.
void(*	feedback )(struct c_context *context, struct c_feedback *feedback)
	The handler used to warn the profile-specific part of the context about the arrival of feedback data.
