Server Header
[SIP Headers]

Collaboration diagram for Server Header:


Detailed Description

The Server response-header field contains information about the software used by the user agent server to handle the request.

Its syntax is defined in [H14.38, S10.39] as follows:

    Server           =  "Server" HCOLON server-val *(LWS server-val)
    server-val       =  product / comment
    product          =  token [SLASH product-version]
    product-version  =  token

Define Documentation

 
#define SIP_SERVER_INIT (  ) 

Initializer for structure sip_server_t.

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

#define SIPTAG_SERVER (  ) 

Tag list item for pointer to a Server header structure.

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

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

#define SIPTAG_SERVER_STR (  ) 

Tag list item for string with Server header value.

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

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

The corresponding tag taking reference parameter is SIPTAG_SERVER_STR_REF().

Function Documentation

int sip_is_server ( sip_header_t const *  header  )  [inline]

Test if header object is instance of sip_server_t.

The function sip_is_server() returns true (nonzero) if the header class is an instance of Server header object and false (zero) otherwise.

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

sip_server_t * sip_server_copy ( su_home_t home,
sip_server_t const *  hdr 
) [inline]

Copy a sip_server_t header structure.

The function sip_server_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
   server = sip_server_copy(home, sip->sip_server);
Returns:
The function sip_server_copy() returns a pointer to newly copied header structure, or NULL upon an error.

sip_server_t * sip_server_dup ( su_home_t home,
sip_server_t const *  hdr 
) [inline]

Duplicate (deep copy) sip_server_t.

The function sip_server_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
   server = sip_server_dup(home, sip->sip_server);
Returns:
The function sip_server_dup() returns a pointer to the newly duplicated sip_server_t header structure, or NULL upon an error.

sip_server_t * sip_server_format ( su_home_t home,
char const *  fmt,
  ... 
) [inline]

Make a Server header from formatting result.

The function sip_server_format() makes a new Server 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_server_format() returns a pointer to newly makes header structure, or NULL upon an error.

sip_server_t* sip_server_init ( sip_server_t  x[1]  )  [inline]

Initialize a structure sip_server_t.

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

sip_server_t * sip_server_make ( su_home_t home,
char const *  s 
) [inline]

Make a header structure sip_server_t.

The function sip_server_make() makes a new sip_server_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_server_make() returns a pointer to newly maked sip_server_t header structure, or NULL upon an error.


Variable Documentation

msg_hclass_t sip_server_class[]

Header class for SIP Server header.

The header class sip_server_class defines how a SIP Server header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_server_t header structure.
