Function Documentation

const char* rohc_get_ip_proto_descr

(

const uint8_t

protocol

)

Give a description for the given IP protocol.

Parameters:

protocol

The IP protocol to get a description for

Returns:

A string that describes the given IP protocol

bool rohc_is_ipv6_opt

(

const uint8_t

protocol

)

Whether the given protocol is an IPv6 option.

Handle GRE, Authentication (AH), MINE, and all IPv6 extension headers.

The list of IPv6 extension headers was retrieved from the registry maintained by IANA at: http://www.iana.org/assignments/ipv6-parameters/ipv6-parameters.xhtml Remember to update get_index_ipv6_table if you update the list.

Parameters:

protocol

The protocol number to check for

Returns:

true if the protocol is an IPv6 option, false otherwise

bool rohc_is_tunneling

(

const uint8_t

protocol

)

Whether the given protocol is IP tunneling.

Parameters:

protocol

The protocol number to check for

Returns:

true if the protocol is IP/IP or IPv6, false otherwise
