Allow-Event Header
[SIP Headers]

The Allow-Event header is used to indicate which events or classes of events the notifier supports.

Its syntax is defined in RFC 3265 as follows:

    Allow-Events = ( "Allow-Events" | "u" ) ":" 1#event-type

Define Documentation

 
#define SIP_ALLOW_EVENTS_INIT (  ) 

Initializer for structure sip_allow_events_t.

A static sip_allow_events_t structure must be initialized. The SIP_ALLOW_EVENTS_INIT() macro provides initialization value. For instance,

#define SIPTAG_ALLOW_EVENTS (  ) 

Tag list item for pointer to a Allow-Events header structure.

The SIPTAG_ALLOW_EVENTS() macro is used to include a tag item with a pointer to a sip_allow_events_t object in a tag list.

Parameters:
x pointer to a sip_allow_events_t header structure, or NULL.
The corresponding tag taking reference parameter is SIPTAG_ALLOW_EVENTS_REF().

#define SIPTAG_ALLOW_EVENTS_STR (  ) 

Tag list item for string with Allow-Events header value.

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

Parameters:
s pointer to a string containing sip_allow_events_t value, or NULL.
The string in SIPTAG_ALLOW_EVENTS_STR() can be converted to a sip_allow_events_t header structure by giving the string s has second argument to function sip_allow_events_make().

The corresponding tag taking reference parameter is SIPTAG_ALLOW_EVENTS_STR_REF().


Typedef Documentation

struct msg_list_s sip_allow_events_t

The structure sip_allow_events_t contains representation of an Allow-Events header.

The sip_allow_events_t is defined as follows:

 typedef struct msg_list_s
 {
   msg_common_t       k_common[1];  // Common fragment info
   msg_list_t        *k_next;         // Link to next header
   msg_param_t       *k_items;      // List of items
 } sip_allow_events_t;

Function Documentation

sip_allow_events_t * sip_allow_events_copy ( su_home_t home,
sip_allow_events_t const *  hdr 
) [inline]

Copy a sip_allow_events_t header structure.

The function sip_allow_events_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.

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
   allow_events = sip_allow_events_copy(home, sip->sip_allow_events);
Returns:
The function sip_allow_events_copy() returns a pointer to newly copied header structure, or NULL upon an error.

sip_allow_events_t * sip_allow_events_dup ( su_home_t home,
sip_allow_events_t const *  hdr 
) [inline]

Duplicate (deep copy) sip_allow_events_t.

The function sip_allow_events_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.

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
   allow_events = sip_allow_events_dup(home, sip->sip_allow_events);
Returns:
The function sip_allow_events_dup() returns a pointer to the newly duplicated sip_allow_events_t header structure, or NULL upon an error.

sip_allow_events_t * sip_allow_events_format ( su_home_t home,
char const *  fmt,
  ... 
) [inline]

Make a Allow-Events header from formatting result.

The function sip_allow_events_format() makes a new Allow-Events 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.

Parameters:
home memory home used to allocate new header structure.
fmt string used as a printf()-style format
... argument list for format
Note:
This function is usually implemented as a macro calling msg_header_format().
Returns:
The function sip_allow_events_format() returns a pointer to newly makes header structure, or NULL upon an error.

sip_allow_events_t* sip_allow_events_init ( sip_allow_events_t  x[1]  )  [inline]

Initialize a structure sip_allow_events_t.

An sip_allow_events_t structure can be initialized with the sip_allow_events_init() function/macro. For instance,

  sip_allow_events_t sip_allow_events;
 
  sip_allow_events_init(&sip_allow_events);

sip_allow_events_t * sip_allow_events_make ( su_home_t home,
char const *  s 
) [inline]

Make a header structure sip_allow_events_t.

The function sip_allow_events_make() makes a new sip_allow_events_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
Note:
This function is usually implemented as a macro calling sip_header_make().
Returns:
The function sip_allow_events_make() returns a pointer to newly maked sip_allow_events_t header structure, or NULL upon an error.

int sip_is_allow_events ( sip_header_t const *  header  )  [inline]

Test if header object is instance of sip_allow_events_t.

The function sip_is_allow_events() returns true (nonzero) if the header class is an instance of Allow-Events header object and false (zero) otherwise.

Parameters:
header pointer to the header structure to be tested
Returns:
The function sip_is_allow_events() returns true (nonzero) if the header object is an instance of header allow_events and false (zero) otherwise.


Variable Documentation

msg_hclass_t sip_allow_events_class[]

Header class for SIP Allow-Events header.

The header class sip_allow_events_class defines how a SIP Allow-Events header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_allow_events_t header structure.
