◆ HTTP_LAST_MODIFIED_INIT
#define HTTP_LAST_MODIFIED_INIT |
( |
| ) |
|
Initializer for structure http_last_modified_t.
A static http_last_modified_t structure must be initialized with the HTTP_LAST_MODIFIED_INIT() macro. For instance,
#define HTTP_LAST_MODIFIED_INIT()
Initializer for structure http_last_modified_t.
Definition http_protos.h:6092
Date, Expires, If-Modified-Since, If-Unmodified-Since, Last-Modified.
Definition http.h:219
◆ HTTPTAG_LAST_MODIFIED
#define HTTPTAG_LAST_MODIFIED |
( |
| x | ) |
|
Tag list item for pointer to a Last-Modified header object.
The HTTPTAG_LAST_MODIFIED() macro is used to include a tag item with a pointer to a http_last_modified_t object in a tag list.
- Parameters
-
x | pointer to a http_last_modified_t header structure, or NULL. |
◆ HTTPTAG_LAST_MODIFIED_STR
#define HTTPTAG_LAST_MODIFIED_STR |
( |
| s | ) |
|
Tag list item for string with Last-Modified header value.
The HTTPTAG_LAST_MODIFIED_STR() macro is used to include a tag item with a string containing value of a http_last_modified_t header in a tag list.
- Parameters
-
s | pointer to a string containing http_last_modified_t value, or NULL. |
The HTTPTAG_LAST_MODIFIED_STR string can be converted to a http_last_modified_t header structure by giving the string s has second argument to function http_last_modified_make().
◆ http_last_modified_t
@HTTP_HEADER http_last_modified Last-Modified header.
The Last-Modified header field gives the date and time after which the message content last_modified. Its syntax is defined in [] as follows:
Last-Modified = "Last-Modified:" HTTP-date
The structure http_last_modified_t contains representation of Last-Modified header.
The http_last_modified_t is defined as follows:
typedef struct {
http_date_t http_last_modified_t
@HTTP_HEADER http_last_modified Last-Modified header.
Definition http.h:134
unsigned long http_time_t
Time in seconds since 01-Jan-1900.
Definition http.h:169
◆ anonymous enum
Enumerator |
---|
http_last_modified_hash | Hash of Last-Modified header.
|
◆ http_is_last_modified()
Test if header object is instance of http_last_modified_t.
The function http_is_last_modified() returns true (nonzero) if the header class is an instance of Last-Modified header object and false (zero) otherwise.
- Parameters
-
header | pointer to the header structure to be tested |
- Returns
- The function http_is_xlast_modified() returns true (nonzero) if the header object is an instance of header last_modified and false (zero) otherwise.
◆ http_last_modified_copy()
Copy a http_last_modified_t header structure.
The function http_last_modified_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_last_modified_t * http_last_modified_copy(su_home_t *home, http_last_modified_t const *hdr))
Copy a http_last_modified_t header structure.
Definition http_protos.h:6286
- Returns
- The function http_last_modified_copy() returns a pointer to newly copied header structure, or NULL upon an error.
◆ http_last_modified_dup()
Duplicate (deep copy) http_last_modified_t
.
The function http_last_modified_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_last_modified_t * http_last_modified_dup(su_home_t *home, http_last_modified_t const *hdr))
Duplicate (deep copy) http_last_modified_t.
Definition http_protos.h:6279
- Returns
- The function http_last_modified_dup() returns a pointer to the newly duplicated http_last_modified_t header structure, or NULL upon an error.
◆ http_last_modified_format()
Make a Last-Modified header from formatting result.
The function http_last_modified_format() makes a new Last-Modified 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_last_modified_format() returns a pointer to newly makes header structure, or NULL upon an error.
◆ http_last_modified_init()
Initialize a structure http_last_modified_t.
An http_last_modified_t structure can be initialized with the http_last_modified_init() function/macro. For instance,
http_last_modified_t * http_last_modified_init(http_last_modified_t x[1])
Initialize a structure http_last_modified_t.
Definition http_protos.h:6108
◆ http_last_modified_make()
Make a header structure http_last_modified_t.
The function http_last_modified_make() makes a new http_last_modified_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_last_modified_make() returns a pointer to newly maked http_last_modified_t header structure, or NULL upon an error.
◆ http_last_modified_class
Header class for HTTP Last-Modified header.
The header class http_last_modified_class defines how a HTTP Last-Modified header is parsed and printed. It also contains methods used by HTTP parser and other functions to manipulate the http_last_modified_t header structure.
