We use header separator object from msg module.
§ HTTP_SEPARATOR_INIT
#define HTTP_SEPARATOR_INIT |
( |
| ) |
|
Initializer for structure http_separator_t.
A static http_separator_t structure must be initialized with the HTTP_SEPARATOR_INIT() macro. For instance,
§ HTTPTAG_SEPARATOR
#define HTTPTAG_SEPARATOR |
( |
|
x | ) |
|
Tag list item for pointer to a separator line between headers and body object.
The HTTPTAG_SEPARATOR() macro is used to include a tag item with a pointer to a http_separator_t object in a tag list.
- Parameters
-
x | pointer to a http_separator_t header structure, or NULL. |
§ HTTPTAG_SEPARATOR_STR
#define HTTPTAG_SEPARATOR_STR |
( |
|
s | ) |
|
Tag list item for string with separator line between headers and body value.
The HTTPTAG_SEPARATOR_STR() macro is used to include a tag item with a string containing value of a http_separator_t header in a tag list.
- Parameters
-
s | pointer to a string containing http_separator_t value, or NULL. |
The HTTPTAG_SEPARATOR_STR string can be converted to a http_separator_t header structure by giving the string s has second argument to function http_separator_make().
§ anonymous enum
Enumerator |
---|
http_separator_hash | Hash of separator line between headers and body.
|
§ http_is_separator()
Test if header object is instance of http_separator_t.
The function http_is_separator() returns true (nonzero) if the header class is an instance of separator line between headers and body object and false (zero) otherwise.
- Parameters
-
header | pointer to the header structure to be tested |
- Returns
- The function http_is_xseparator() returns true (nonzero) if the header object is an instance of header separator and false (zero) otherwise.
§ http_separator_copy()
Copy a http_separator_t header structure.
The function http_separator_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
- Returns
- The function http_separator_copy() returns a pointer to newly copied header structure, or NULL upon an error.
§ http_separator_dup()
Duplicate (deep copy) http_separator_t
.
The function http_separator_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
- Returns
- The function http_separator_dup() returns a pointer to the newly duplicated http_separator_t header structure, or NULL upon an error.
§ http_separator_format()
Make a separator line between headers and body from formatting result.
The function http_separator_format() makes a new separator line between headers and body 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_separator_format() returns a pointer to newly makes header structure, or NULL upon an error.
§ http_separator_init()
Initialize a structure http_separator_t.
An http_separator_t structure can be initialized with the http_separator_init() function/macro. For instance,
§ http_separator_make()
Make a header structure http_separator_t.
The function http_separator_make() makes a new http_separator_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_separator_make() returns a pointer to newly maked http_separator_t header structure, or NULL upon an error.
§ http_separator_class
Header class for HTTP separator line between headers and body.
The header class http_separator_class defines how a HTTP separator line between headers and body is parsed and printed. It also contains methods used by HTTP parser and other functions to manipulate the http_separator_t header structure.
