Detailed Description

The Security-Verify header is defined by RFC 3329, "Security Mechanism Agreement for the Session Initiation Protocol (SIP)".

See also:
Security-Client, Security-Server, sip_security_verify_compare(), sip_security_client_select(), RFC 3329.

The parsed Security-Verify header is stored in sip_security_verify_t structure.


Define Documentation

#define SIP_SECURITY_VERIFY_INIT (  ) 

Initializer for structure sip_security_verify_t.

A static sip_security_verify_t structure for Security-Verify header must be initialized with the SIP_SECURITY_VERIFY_INIT() macro. For instance,

  sip_security_verify_t sip_security_verify = SIP_SECURITY_VERIFY_INIT;
#define SIPTAG_SECURITY_VERIFY (   x  ) 

Tag list item for pointer to a Security-Verify header structure sip_security_verify_t.

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

Parameters:
x pointer to a sip_security_verify_t structure, or NULL.

The corresponding tag taking reference parameter is SIPTAG_SECURITY_VERIFY_REF().

#define SIPTAG_SECURITY_VERIFY_STR (   s  ) 

Tag list item for string with Security-Verify header value.

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

Parameters:
s pointer to a string containing Security-Verify header value, or NULL.

The string in SIPTAG_SECURITY_VERIFY_STR() can be converted to a sip_security_verify_t header structure by giving the string s has second argument to function sip_security_verify_make().

The corresponding tag taking reference parameter is SIPTAG_SECURITY_VERIFY_STR_REF().


Typedef Documentation

typedef struct sip_security_verify_s sip_security_verify_t

The structure sip_security_verify_t contains representation of SIP Security-Verify header.

The sip_security_verify_t is defined as follows:

 typedef struct sip_security_agree_s
 {
   sip_common_t        sa_common[1]; // Common fragment info
   sip_security_verify_t *sa_next;   // Link to next mechanism
   char const         *sa_mec;       // Security mechanism
   msg_param_t const  *sa_params;    // List of mechanism parameters
   char const         *sa_q;         // Value of q (preference) parameter
   char const         *sa_d_alg;     // Value of d-alg parameter
   char const         *sa_d_qop;     // Value of d-qop parameter
   char const         *sa_d_ver;     // Value of d-ver parameter
 } sip_security_verify_t;

Function Documentation

int sip_is_security_verify ( sip_header_t const *  header  )  [inline]

Test if header object is instance of sip_security_verify_t.

Check if the header class is an instance of Security-Verify 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 security_verify
0 (false) otherwise
sip_security_verify_t * sip_security_verify_copy ( su_home_t home,
sip_security_verify_t const *  hdr 
) [inline]

Copy a list of Security-Verify header header structures sip_security_verify_t.

The function sip_security_verify_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
   security_verify = sip_security_verify_copy(home, sip->sip_security_verify);
Returns:
A pointer to newly copied header structure, or NULL upon an error.
sip_security_verify_t * sip_security_verify_dup ( su_home_t home,
sip_security_verify_t const *  hdr 
) [inline]

Duplicate a list of Security-Verify header header structures sip_security_verify_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
   security_verify = sip_security_verify_dup(home, sip->sip_security_verify);
Returns:
A pointer to the newly duplicated sip_security_verify_t header structure, or NULL upon an error.
sip_security_verify_t * sip_security_verify_format ( su_home_t home,
char const *  fmt,
  ... 
) [inline]

Make a Security-Verify header from formatting result.

Make a new sip_security_verify_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_security_verify_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_security_verify_t* sip_security_verify_init ( sip_security_verify_t  x[1]  )  [inline]

Initialize a structure sip_security_verify_t.

An sip_security_verify_t structure for Security-Verify header can be initialized with the sip_security_verify_init() function/macro. For instance,

  sip_security_verify_t sip_security_verify;

  sip_security_verify_init(&sip_security_verify);
sip_security_verify_t * sip_security_verify_make ( su_home_t home,
char const *  s 
) [inline]

Make a Security-Verify header structure sip_security_verify_t.

The function sip_security_verify_make() makes a new sip_security_verify_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_security_verify_t header structure, or NULL upon an error.

Variable Documentation

Header class for Security-Verify header.

The header class sip_security_verify_class defines how a SIP Security-Verify header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_security_verify_t header structure.
