◆ SIP_CALL_INFO_INIT

Initializer for structure sip_call_info_t.
A static sip_call_info_t structure for Call-Info header must be initialized with the SIP_CALL_INFO_INIT() macro. For instance,
#define SIP_CALL_INFO_INIT()
Initializer for structure sip_call_info_t.
Definition sip_protos.h:5860
#define sip_call_info(sip)
Access a SIP Call-Info header structure sip_call_info_t from sip_t.
Definition sip_protos.h:5843
Structure for Call-Info header.
Definition sip.h:449

◆ sip_call_info_t
@
The Call-Info header provides additional information about the caller or callee. Its syntax is defined in RFC 3261 as follows:
Call-Info = "Call-Info" HCOLON info *(COMMA info)
info = LAQUOT absoluteURI RAQUOT *( SEMI info-param)
info-param = ( "purpose" EQUAL ( "icon" / "info"
/ "card" / token ) ) / generic-param
The parsed Call-Info header is stored in sip_call_info_t structure.
The structure sip_call_info_t contains representation of an Call-Info header.
The sip_call_info_t is defined as follows:
{
};
msg_param_t const * ci_params
List of parameters.
Definition sip.h:453
url_t ci_url[1]
URI to call info
Definition sip.h:452
sip_call_info_t * ci_next
Link to next Call-Info.
Definition sip.h:451
sip_common_t ci_common[1]
Common fragment info.
Definition sip.h:450
char const * ci_purpose
Value of purpose parameter.
Definition sip.h:454
◆ sip_call_info_copy()
Copy a list of Call-Info header header structures sip_call_info_t.
The function sip_call_info_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 list of header structure hdr.
- Parameters
-
home | memory home used to allocate new structure |
hdr | pointer to the header structure to be copied |
When copying, only the header structure and parameter lists attached to it are duplicated. The new header structure retains all the references to the strings within the old hdr header, including the encoding of the old header, if present.
- Example
sip_call_info_t * sip_call_info_copy(su_home_t *home, sip_call_info_t const *hdr))
Copy a list of Call-Info header header structures sip_call_info_t.
Definition sip_protos.h:5990
- Returns
- A pointer to newly copied header structure, or NULL upon an error.
◆ sip_call_info_dup()
Duplicate a list of Call-Info header header structures sip_call_info_t.
Duplicate 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.
- Parameters
-
home | memory home used to allocate new structure |
hdr | header structure to be duplicated |
When duplicating, all parameter lists and non-constant strings attached to the header are copied, too. The function uses given memory home to allocate all the memory areas used to copy the header.
- Example
sip_call_info_t * sip_call_info_dup(su_home_t *home, sip_call_info_t const *hdr))
Duplicate a list of Call-Info header header structures sip_call_info_t.
Definition sip_protos.h:5947
- Returns
- A pointer to the newly duplicated sip_call_info_t header structure, or NULL upon an error.
◆ sip_call_info_format()
Make a Call-Info header from formatting result.
Make a new sip_call_info_t 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 parses the formatting result to the structure sip_call_info_t.
- Parameters
-
home | memory home used to allocate new header structure. |
fmt | string used as a printf()-style format |
... | argument list for format |
- Returns
- A pointer to newly makes header structure, or NULL upon an error.
◆ sip_call_info_init()
◆ sip_call_info_make()
Make a Call-Info header structure sip_call_info_t.
The function sip_call_info_make() makes a new sip_call_info_t header structure. It allocates a new header structure, and decodes the string s as the value of the structure.
- Parameters
-
home | memory home used to allocate new header structure. |
s | string to be decoded as value of the new header structure |
- Returns
- A pointer to newly maked sip_call_info_t header structure, or NULL upon an error.
◆ sip_is_call_info()
Test if header object is instance of sip_call_info_t.
Check if the header class is an instance of Call-Info header object and return true (nonzero), otherwise return false (zero).
- Parameters
-
header | pointer to the header structure to be tested |
- Return values
-
1 | (true) if the header is an instance of header call_info |
0 | (false) otherwise |
◆ sip_call_info_class
Header class for Call-Info header.
The header class sip_call_info_class defines how a SIP Call-Info header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_call_info_t header structure.
