◆ HTTP_ETAG_INIT
#define HTTP_ETAG_INIT |
( |
| ) |
|
Initializer for structure http_etag_t.
A static http_etag_t structure must be initialized with the HTTP_ETAG_INIT() macro. For instance,
#define HTTP_ETAG_INIT()
Initializer for structure http_etag_t.
Definition http_protos.h:3592
◆ HTTPTAG_ETAG
#define HTTPTAG_ETAG |
( |
| x | ) |
|
Tag list item for pointer to a ETag header object.
The HTTPTAG_ETAG() macro is used to include a tag item with a pointer to a http_etag_t object in a tag list.
- Parameters
-
x | pointer to a http_etag_t header structure, or NULL. |
◆ HTTPTAG_ETAG_STR
#define HTTPTAG_ETAG_STR |
( |
| s | ) |
|
Tag list item for string with ETag header value.
The HTTPTAG_ETAG_STR() macro is used to include a tag item with a string containing value of a http_etag_t header in a tag list.
- Parameters
-
s | pointer to a string containing http_etag_t value, or NULL. |
The HTTPTAG_ETAG_STR string can be converted to a http_etag_t header structure by giving the string s has second argument to function http_etag_make().

◆ http_etag_copy()
http_etag_t * http_etag_copy |
( |
su_home_t * | home, |
|
|
http_etag_t const * | hdr ) |
|
inline |
Copy a http_etag_t header structure.
The function http_etag_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 duplicated |
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 header, including the encoding of the old header, if present.
- Example
http_etag_t * http_etag_copy(su_home_t *home, http_etag_t const *hdr))
Copy a http_etag_t header structure.
Definition http_protos.h:3786
- Returns
- The function http_etag_copy() returns a pointer to newly copied header structure, or NULL upon an error.
◆ http_etag_dup()
http_etag_t * http_etag_dup |
( |
su_home_t * | home, |
|
|
http_etag_t const * | hdr ) |
|
inline |
Duplicate (deep copy) http_etag_t
.
The function http_etag_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
http_etag_t * http_etag_dup(su_home_t *home, http_etag_t const *hdr))
Duplicate (deep copy) http_etag_t.
Definition http_protos.h:3779
- Returns
- The function http_etag_dup() returns a pointer to the newly duplicated http_etag_t header structure, or NULL upon an error.
◆ http_etag_format()
http_etag_t * http_etag_format |
( |
su_home_t * | home, |
|
|
char const * | fmt, |
|
|
| ... ) |
|
inline |
Make a ETag header from formatting result.
The function http_etag_format() makes a new ETag 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 http_etag_format() returns a pointer to newly makes header structure, or NULL upon an error.
◆ http_etag_init()
http_etag_t * http_etag_init |
( |
http_etag_t | x[1] | ) |
|
|
inline |
Initialize a structure http_etag_t.
An http_etag_t structure can be initialized with the http_etag_init() function/macro. For instance,
http_etag_t http_etag;
http_etag_t * http_etag_init(http_etag_t x[1])
Initialize a structure http_etag_t.
Definition http_protos.h:3608
◆ http_etag_make()
http_etag_t * http_etag_make |
( |
su_home_t * | home, |
|
|
char const * | s ) |
|
inline |
Make a header structure http_etag_t.
The function http_etag_make() makes a new http_etag_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 http_header_make().
- Returns
- The function http_etag_make() returns a pointer to newly maked http_etag_t header structure, or NULL upon an error.
◆ http_is_etag()
Test if header object is instance of http_etag_t.
The function http_is_etag() returns true (nonzero) if the header class is an instance of ETag header object and false (zero) otherwise.
- Parameters
-
header | pointer to the header structure to be tested |
- Returns
- The function http_is_xetag() returns true (nonzero) if the header object is an instance of header etag and false (zero) otherwise.
◆ http_etag_class
Header class for HTTP ETag header.
The header class http_etag_class defines how a HTTP ETag header is parsed and printed. It also contains methods used by HTTP parser and other functions to manipulate the http_etag_t header structure.
