For each of the following functions that add a header to a SIP message, the function adds a CRLF before appending the header to the SIP message. The sip_add_from() and sip_add_to() functions appends a FROM and TO header respectively to the SIP message sip_msg. The header is created using the display_name, if non-null, and the uri values. The add_aquot parameter is used to specify whether the uri should be enclosed within '<>'. If a display_name is provided then add_aquot cannot be B_FALSE. The display_name parameter, if provided, is enclosed within quotes before creating to the SIP header. Tag value for the FROM/TO header can be specified which will be added to the SIP header by pre- fixing it with "TAG=". Any generic parameters can be specified as the last argument, which will be added, as is, to the SIP header. Either the tag or the generic parameter can be specified not both, if both are specified, the resulting header contains only the tag param- eter. The sip_add_contact() function appends a CONTACT header to the SIP message sip_msg using the display_name and contact_uri. The add_aquot parameter has the same semantics as in sip_add_from()/sip_add_to(). Any contact parameters specified in contact_param is added to the CON- TACT header before appending the header to the message. The sip_add_via() function appends a VIA header to the SIP message sip_msg. The VIA header is constructed using sent_protocol_transport, sent_by_host and sent_by_port. A value of 0 for sent_by_port means that the port information is not present in the resulting VIA header. The VIA header that is created has the protocol set to "SIP" and version set to "2.0". Any parameters specific in via_params is added to the VIA header before appending the header to the SIP message. The sip_add_maxforward() function appends a MAX-FORWARDS header to the SIP message sip_msg using the value in maxforward. The maxforward value is a positive integer. The sip_add_callid() function appends a CALL-ID header to the SIP message sip_msg using the value in callid, if non-null. If callid is null, this function creates a CALL-ID header using a randomly generated value. The sip_add_cseq() function appends a CSEQ header to the SIP message using the values in method and cseq. Permissible values for method include: INVITE ACK OPTIONS BYE CANCEL REGISTER REFER SUBSCRIBE NOTIFY PRACK INFO The cseq value is a positive integer. The sip_add_content_type() function appends a CONTENT-TYPE to the SIP message sip_msg. The CONTENT-TYPE is created using the type and sub- type, both should be non-null. The sip_add_content() function adds a message body to the SIP message sip_msg. The message body is given by the null terminated string con- tents. Once the function returns, the caller may reuse or delete contents as sip_add_content() creates a new buffer and copies over con- tents for its use. The sip_add_accept() function appends an ACCEPT header to the SIP message sip_msg. The ACCEPT header is created using type and subtype. If both type and subtype are null, then an empty ACCEPT header is added to the SIP message. If type is non-null, but subtype is null, then the ACCEPT header has the specified type and sets the subtype in the header to '*'. Any accept_param or media_param, if provided, are added to the ACCEPT header before appending the header to the SIP message. The sip_add_accept_enc() function appends an ACCEPT-ENCODING header to the SIP message sip_msg. The ACCEPT-ENCODING is created using code. Any parameter specified in param is added to the ACCEPT-ENCODING header before appending the header to the SIP message. The sip_add_accept_lang() function appends an ACCEPT-LANGUAGE header to the SIP message sip_msg. The ACCEPT-LANGUAGE header is created using lang. Any parameter specified in param is added to the ACCEPT-LANGUAGE header before appending the header to the SIP message.
