Detailed Description

Macro Definition Documentation

HTTP_VIA_INIT

#define HTTP_VIA_INIT

(

)

Initializer for structure http_via_t.

A static http_via_t structure must be initialized with the HTTP_VIA_INIT() macro. For instance,

http_via_t http_via = HTTP_VIA_INIT;

HTTPTAG_VIA

#define HTTPTAG_VIA

(

x

)

Tag list item for pointer to a Via header object.

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

Parameters

x	pointer to a http_via_t header structure, or NULL.

HTTPTAG_VIA_STR

#define HTTPTAG_VIA_STR

(

s

)

Tag list item for string with Via header value.

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

Parameters

s	pointer to a string containing http_via_t value, or NULL.

The HTTPTAG_VIA_STR string can be converted to a http_via_t header structure by giving the string s has second argument to function http_via_make().

Enumeration Type Documentation

anonymous enum

anonymous enum

Enumerator
http_via_hash	Hash of Via header.

Function Documentation

http_is_via()

int http_is_via ( http_header_t const *  header )

inline

Test if header object is instance of http_via_t.

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

Parameters

header

pointer to the header structure to be tested

Returns

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

http_via_copy()

http_via_t * http_via_copy ( su_home_t *  home, http_via_t const *  hdr  )
