NAME
sip_register_sent_by, sip_unregister_sent_by, sip_unregister_all_sent_by - allows registering and un-registering sent-by values SYNOPSIS
cc [ flag ... ] file ... -lsip [ library ... ] #include <sip.h> int sip_register_sent_by(char *val); void sip_unregister_sent_by(char *val); void sip_unregister_all_sent_by(int *error); DESCRIPTION
The sip_register_sent_by() function can be used to register a list of hostnames or IP addresses that the application may add to the VIA headers. The val is a comma separated list of such sent-by values. If any value is registered using sip_register_sent_by(), the SIP stack validates incoming responses to check if the sent-by parameter in the topmost VIA header is part of the registered list. If the check fails, the response is dropped. If there are no sent-by values registered, there is no check done on incoming responses. The sip_unregister_sent_by() and sip_unregister_all_sent_by() functions are used to un-register sent-by values. The val for sip_unregis- ter_sent_by() is a comma separated list of sent-by values that need to be un-registered. sip_unregister_all_sent_by() un-registers all the values that have been registered. RETURN VALUES
The sip_register_sent_by() function returns 0 on success and the appropriate error value on failure. The value of errno is not changed by these calls in the event of an error. ATTRIBUTES

NAME
sip_msg_to_str, sip_hdr_to_str, sip_reqline_to_str, sip_respline_to_str, sip_sent_by_to_str - return string representations SYNOPSIS
cc [ flag ... ] file ... -lsip [ library ... ] #include <sip.h> char *sip_msg_to_str(sip_msg_t sip_msg, int *error); char *sip_hdr_to_str(sip_header_t sip_header, int *error); char *sip_reqline_to_str(sip_msg_t sip_msg, int *error); char *sip_respline_to_str(sip_msg_t sip_msg, int *error); char *sip_sent_by_to_str(int *error); DESCRIPTION
The sip_msg_to_str() function returns the string representation of the SIP message sip_msg. Deleted headers are not included in the returned string. The caller is responsible for freeing the returned string. The sip_hdr_to_str() function returns the string representation of the SIP header sip_header. The caller is responsible for freeing the returned string. The sip_reqline_to_str() function returns the string representation of the request line from the SIP message sip_msg. The caller is respon- sible for freeing the returned string. The sip_respline_to_str() function returns the string representation of the response line from the SIP message sip_msg. The caller is responsible for freeing the returned string. The sip_sent_by_to_str() function can be used to retrieve the list of sent-by values registered with the stack. The returned string is a comma separated list of sent-by values. The caller is responsible for freeing the returned string. RETURN VALUES
The sip_msg_to_str(), sip_hdr_to_str(), sip_reqline_to_str(), sip_respline_to_str(), and sip_sent_by_to_str() functions return the relevant string on success and NULL on failure. The value of errno is not changed by these calls in the event of an error. ERRORS
For the sip_msg_to_str(), sip_hdr_to_str(), sip_reqline_to_str(), and sip_respline_to_str(), one of the following values is set if the error is non-null: EINVAL Input is null. ENOMEM Memory allocation failure. On success, the value of the location pointed to by error is set to 0. ATTRIBUTES
