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,

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 responsible 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.

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.

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

ENOMEM

On success, the value of the location pointed to by error is set to 0.
