#include <sip.h>

const sip_str_t *sip_get_request_uri_str(sip_msg_t sip_msg, 
     int *error);

Description

For functions that return a pointer of type sip_str_t, sip_str_t is supplied by:

typedef struct sip_str {
     char *sip_str_ptr;
     int  sip_str_len;
}sip_str_t;

The sip_str_ptr parameter points to the start of the returned value and sip_str_len supplies the length of the returned value.

For example, given the following request line in a SIP message input to sip_get_request_uri_str():

INVITE sip:marconi@radio.org SIP/2.0

the return is a pointer to sip_str_t with the sip_str_ptr member pointing to “s” of sip:marconi@radio.org and sip_str_len being set to 21, the length of sip:marconi@radio.org.

The sip_get_request_uri_str() function returns the URI string from the request line in the SIP message sip_msg.
