#define SIP_SUPPORTED_INIT | ( | ) |
Initializer for structure sip_supported_t.
A static sip_supported_t structure for Supported header must be initialized with the SIP_SUPPORTED_INIT() macro. For instance,
#define SIPTAG_SUPPORTED | ( | x | ) |
Tag list item for pointer to a Supported header structure sip_supported_t.
The SIPTAG_SUPPORTED() macro is used to include a tag item with a pointer to a sip_supported_t structure in a tag list.
x | pointer to a sip_supported_t structure, or NULL. |
The corresponding tag taking reference parameter is SIPTAG_SUPPORTED_REF().
#define SIPTAG_SUPPORTED_REF | ( | x | ) |
Tag list item for reference to a Supported header pointer.
#define SIPTAG_SUPPORTED_STR | ( | s | ) |
Tag list item for string with Supported header value.
The SIPTAG_SUPPORTED_STR() macro is used to include a tag item with a string containing value of a sip_supported_t header in a tag list.
s | pointer to a string containing Supported header value, or NULL. |
The string in SIPTAG_SUPPORTED_STR() can be converted to a sip_supported_t header structure by giving the string s has second argument to function sip_supported_make().
The corresponding tag taking reference parameter is SIPTAG_SUPPORTED_STR_REF().
#define SIPTAG_SUPPORTED_STR_REF | ( | x | ) |
Tag list item for reference to a Supported header string.
struct msg_list_s sip_supported_t |
@
The Supported header enumerates all the capabilities of the client or server. Its syntax is defined in RFC 3261 as follows:
The parsed option-tags of Supported header are stored in sip_supported_t structure.
The structure sip_supported_t contains representation of an Supported header.
The sip_supported_t is defined as follows:
|
inline |
Test if header object is instance of sip_supported_t.
Check if the header class is an instance of Supported header object and return true (nonzero), otherwise return false (zero).
header | pointer to the header structure to be tested |
1 | (true) if the header is an instance of header supported |
0 | (false) otherwise |
|
inline |
Copy a list of Supported header header structures sip_supported_t.
The function sip_supported_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.
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.
|
inline |
Duplicate a list of Supported header header structures sip_supported_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.
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.
|
inline |
Make a Supported header from formatting result.
Make a new sip_supported_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_supported_t.
home | memory home used to allocate new header structure. |
fmt | string used as a printf()-style format |
... | argument list for format |
|
inline |
Initialize a structure sip_supported_t.
An sip_supported_t structure for Supported header can be initialized with the sip_supported_init() function/macro. For instance,
|
inline |
Make a Supported header structure sip_supported_t.
The function sip_supported_make() makes a new sip_supported_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 |
msg_hclass_t sip_supported_class[] |
Header class for Supported header.
The header class sip_supported_class defines how a SIP Supported header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_supported_t header structure.
tag_typedef_t siptag_supported |
Tag for Supported header object.
tag_typedef_t siptag_supported_str |
Tag for string with Supported header value.
