Its syntax is defined in [S10.13] 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

#define SIP_CALL_INFO_INIT | ( | ) |
Initializer for structure sip_call_info_t.
A static sip_call_info_t structure must be initialized. The SIP_CALL_INFO_INIT() macro provides initialization value. For instance,
#define SIPTAG_CALL_INFO | ( | x | ) |
Tag list item for pointer to a Call-Info header structure.
The SIPTAG_CALL_INFO() macro is used to include a tag item with a pointer to a sip_call_info_t object in a tag list.
x | pointer to a sip_call_info_t header structure, or NULL. |
#define SIPTAG_CALL_INFO_STR | ( | s | ) |
Tag list item for string with Call-Info header value.
The SIPTAG_CALL_INFO_STR() macro is used to include a tag item with a string containing value of a sip_call_info_t header in a tag list.
s | pointer to a string containing sip_call_info_t value, or NULL. |
The corresponding tag taking reference parameter is SIPTAG_CALL_INFO_STR_REF().
struct sip_call_info_s sip_call_info_t |
The structure sip_call_info_t contains representation of an Call-Info header.
The sip_call_info_t is defined as follows:
struct sip_call_info_s { sip_common_t ci_common[1]; // Common fragment info sip_call_info_t *ci_next; // Link to next Call-Info url_t ci_url[1]; // URI to call info msg_param_t const *ci_params; // List of parameters msg_param_t ci_purpose; // Value of @b purpose parameter };
sip_call_info_hash |
@
Hash of Call-Info header.
sip_call_info_t * sip_call_info_copy | ( | su_home_t * | home, | |
sip_call_info_t const * | hdr | |||
) | [inline] |
Copy a sip_call_info_t header structure.
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 header structure hdr.
home | memory home used to allocate new structure | |
hdr | pointer to the header structure to be copied |
call_info = sip_call_info_copy(home, sip->sip_call_info);
sip_call_info_t * sip_call_info_dup | ( | su_home_t * | home, | |
sip_call_info_t const * | hdr | |||
) | [inline] |
Duplicate (deep copy) sip_call_info_t
.
The function sip_call_info_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 |
call_info = sip_call_info_dup(home, sip->sip_call_info);
sip_call_info_t * sip_call_info_format | ( | su_home_t * | home, | |
char const * | fmt, | |||
... | ||||
) | [inline] |
Make a Call-Info header from formatting result.
The function sip_call_info_format() makes a new Call-Info 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_call_info_t* sip_call_info_init | ( | sip_call_info_t | x[1] | ) | [inline] |
Initialize a structure sip_call_info_t.
An sip_call_info_t structure can be initialized with the sip_call_info_init() function/macro. For instance,
sip_call_info_t * sip_call_info_make | ( | su_home_t * | home, | |
char const * | s | |||
) | [inline] |
Make a 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.
home | memory home used to allocate new header structure. | |
s | string to be decoded as value of the new header structure |
int sip_is_call_info | ( | sip_header_t const * | header | ) | [inline] |
Test if header object is instance of sip_call_info_t.
The function sip_is_call_info() returns true (nonzero) if the header class is an instance of Call-Info header object and false (zero) otherwise.
header | pointer to the header structure to be tested |
Header class for SIP 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.
