Detailed Description

The Reject-Contact syntax is defined in RFC 3841 section 10 as follows:

    Reject-Contact  =  ("Reject-Contact" / "j") HCOLON rc-value
                       *(COMMA rc-value)
    rc-value        =  "*" *(SEMI rc-params)
    rc-params       =  feature-param / generic-param
                        ;;feature param from RFC 3840
                        ;;generic-param from RFC 3261

Despite the BNF, there MUST NOT be more than one instance of any feature tag in feature-param.

See also:: RFC 3840, RFC 3841, sip_contact_reject(), sip_contact_score().

The parsed Reject-Contact header is stored in sip_reject_contact_t structure.

Define Documentation

#define SIP_REJECT_CONTACT_INIT ( )

Initializer for structure sip_reject_contact_t.

A static sip_reject_contact_t structure for Reject-Contact header must be initialized with the SIP_REJECT_CONTACT_INIT() macro. For instance,

  sip_reject_contact_t sip_reject_contact = SIP_REJECT_CONTACT_INIT;

#define SIPTAG_REJECT_CONTACT ( x )

Tag list item for pointer to a Reject-Contact header structure sip_reject_contact_t.

The SIPTAG_REJECT_CONTACT() macro is used to include a tag item with a pointer to a sip_reject_contact_t structure in a tag list.

Parameters:

x

pointer to a sip_reject_contact_t structure, or NULL.

The corresponding tag taking reference parameter is SIPTAG_REJECT_CONTACT_REF().

#define SIPTAG_REJECT_CONTACT_STR ( s )

Tag list item for string with Reject-Contact header value.

The SIPTAG_REJECT_CONTACT_STR() macro is used to include a tag item with a string containing value of a sip_reject_contact_t header in a tag list.

Parameters:

s

pointer to a string containing Reject-Contact header value, or NULL.

The string in SIPTAG_REJECT_CONTACT_STR() can be converted to a sip_reject_contact_t header structure by giving the string s has second argument to function sip_reject_contact_make().

The corresponding tag taking reference parameter is SIPTAG_REJECT_CONTACT_STR_REF().

Typedef Documentation

struct sip_caller_prefs_s sip_reject_contact_t

The structure sip_reject_contact_t contains representation of SIP Reject-Contact header.

The sip_reject_contact_t is defined as follows:

 typedef struct caller_prefs_s {
   sip_common_t        cp_common[1];   // Common fragment info
   sip_caller_prefs_t *cp_next;        // Link to next rc-value
   msg_param_t const  *cp_params;      // List of parameters
 } sip_reject_contact_t;

Note:: Fields cp_q, cp_require and cp_explicit are ignored for Reject-Contact header.

Function Documentation

int sip_is_reject_contact ( sip_header_t const * header ) [inline]

Test if header object is instance of sip_reject_contact_t.

Check if the header class is an instance of Reject-Contact 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 reject_contact
	0	(false) otherwise

sip_reject_contact_t * sip_reject_contact_copy	(	su_home_t *	home,
		sip_reject_contact_t const *	hdr
	)			`[inline]`

Copy a list of Reject-Contact header header structures sip_reject_contact_t.

The function sip_reject_contact_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

   reject_contact = sip_reject_contact_copy(home, sip->sip_reject_contact);

Returns:: A pointer to newly copied header structure, or NULL upon an error.

sip_reject_contact_t * sip_reject_contact_dup	(	su_home_t *	home,
		sip_reject_contact_t const *	hdr
	)			`[inline]`

Duplicate a list of Reject-Contact header header structures sip_reject_contact_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

   reject_contact = sip_reject_contact_dup(home, sip->sip_reject_contact);

Returns:: A pointer to the newly duplicated sip_reject_contact_t header structure, or NULL upon an error.

sip_reject_contact_t * sip_reject_contact_format	(	su_home_t *	home,
		char const *	fmt,
			...
	)			`[inline]`

Make a Reject-Contact header from formatting result.

Make a new sip_reject_contact_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_reject_contact_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_reject_contact_t* sip_reject_contact_init ( sip_reject_contact_t x[1] ) [inline]

Initialize a structure sip_reject_contact_t.

An sip_reject_contact_t structure for Reject-Contact header can be initialized with the sip_reject_contact_init() function/macro. For instance,

  sip_reject_contact_t sip_reject_contact;

  sip_reject_contact_init(&sip_reject_contact);

sip_reject_contact_t * sip_reject_contact_make	(	su_home_t *	home,
		char const *	s
	)			`[inline]`

Make a Reject-Contact header structure sip_reject_contact_t.

The function sip_reject_contact_make() makes a new sip_reject_contact_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_reject_contact_t header structure, or NULL upon an error.

Variable Documentation

msg_hclass_t sip_reject_contact_class[]

Header class for Reject-Contact header.

The header class sip_reject_contact_class defines how a SIP Reject-Contact header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_reject_contact_t header structure.
