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.
