Collaboration diagram for Service-Route Header:
![]() |
A registrar may use a Service-Route header field to inform a UA of a service route that, if used by the UA, will provide services from a proxy or set of proxies associated with that registrar. The Service-Route header field may be included by a registrar in the response to a REGISTER request. The syntax for the Service-Route header field is:
Service-Route = "Service-Route" HCOLON sr-value *(COMMA sr-value)
sr-value = name-addr *( SEMI rr-param )

#define SIP_SERVICE_ROUTE_INIT | ( | ) |
Initializer for structure sip_service_route_t.
A static sip_service_route_t structure must be initialized. The SIP_SERVICE_ROUTE_INIT() macro provides initialization value. For instance,
#define SIPTAG_SERVICE_ROUTE | ( | x | ) |
Tag list item for pointer to a Service-Route header structure.
The SIPTAG_SERVICE_ROUTE() macro is used to include a tag item with a pointer to a sip_service_route_t object in a tag list.
x | pointer to a sip_service_route_t header structure, or NULL. |
#define SIPTAG_SERVICE_ROUTE_STR | ( | s | ) |
Tag list item for string with Service-Route header value.
The SIPTAG_SERVICE_ROUTE_STR() macro is used to include a tag item with a string containing value of a sip_service_route_t header in a tag list.
s | pointer to a string containing sip_service_route_t value, or NULL. |
The corresponding tag taking reference parameter is SIPTAG_SERVICE_ROUTE_STR_REF().
typedef struct sip_route_s sip_service_route_t |
The structure sip_service_route_t contains representation of SIP Service-Route header.
The sip_service_route_t is defined as follows:
typedef struct sip_route_s { sip_common_t r_common[1]; // Common fragment info sip_service_route_t*r_next; // Link to next Service-Route char const *r_display; // Display name url_t r_url[1]; // Service-Route URL msg_param_t const *r_params; // List of parameters } sip_service_route_t;
sip_service_route_hash |
@
Hash of Service-Route header.
int sip_is_service_route | ( | sip_header_t const * | header | ) | [inline] |
Test if header object is instance of sip_service_route_t.
The function sip_is_service_route() returns true (nonzero) if the header class is an instance of Service-Route header object and false (zero) otherwise.
header | pointer to the header structure to be tested |
sip_service_route_t * sip_service_route_copy | ( | su_home_t * | home, | |
sip_service_route_t const * | hdr | |||
) | [inline] |
Copy a sip_service_route_t header structure.
The function sip_service_route_copy() copies a header structure hdr. If the header structure hdr contains a reference (hdr->h_next
) to a list of headers, all the headers in that list are copied, too. The function uses given memory home to allocate all the memory areas used to copy the header structure hdr.
home | memory home used to allocate new structure | |
hdr | pointer to the header structure to be copied |
service_route = sip_service_route_copy(home, sip->sip_service_route);
sip_service_route_t * sip_service_route_dup | ( | su_home_t * | home, | |
sip_service_route_t const * | hdr | |||
) | [inline] |
Duplicate (deep copy) sip_service_route_t
.
The function sip_service_route_dup() duplicates a header structure hdr. If the header structure hdr contains a reference (hdr->x_next
) to a list of headers, all the headers in the list are duplicated, too.
home | memory home used to allocate new structure | |
hdr | header structure to be duplicated |
service_route = sip_service_route_dup(home, sip->sip_service_route);
sip_service_route_t * sip_service_route_format | ( | su_home_t * | home, | |
char const * | fmt, | |||
... | ||||
) | [inline] |
Make a Service-Route header from formatting result.
The function sip_service_route_format() makes a new Service-Route header object using formatting result as its value. The function first prints the arguments according to the format fmt specified. Then it allocates a new header structure, and uses the formatting result as the header value.
home | memory home used to allocate new header structure. | |
fmt | string used as a printf()-style format | |
... | argument list for format |
sip_service_route_t* sip_service_route_init | ( | sip_service_route_t | x[1] | ) | [inline] |
Initialize a structure sip_service_route_t.
An sip_service_route_t structure can be initialized with the sip_service_route_init() function/macro. For instance,
sip_service_route_t * sip_service_route_make | ( | su_home_t * | home, | |
char const * | s | |||
) | [inline] |
Make a header structure sip_service_route_t.
The function sip_service_route_make() makes a new sip_service_route_t header structure. It allocates a new header structure, and decodes the string s as the value of the structure.
home | memory home used to allocate new header structure. | |
s | string to be decoded as value of the new header structure |
Header class for SIP Service-Route header.
The header class sip_service_route_class defines how a SIP Service-Route header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_service_route_t header structure.
