Define Documentation

#define HTTP_TRANSFER_ENCODING_INIT

(

)

Initializer for structure http_transfer_encoding_t.

A static http_transfer_encoding_t structure must be initialized with the HTTP_TRANSFER_ENCODING_INIT() macro. For instance,

  http_transfer_encoding_t http_transfer_encoding = HTTP_TRANSFER_ENCODING_INIT;

#define HTTPTAG_TRANSFER_ENCODING

(

x

)

Tag list item for pointer to a Transfer-Encoding header object.

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

Parameters:

x

pointer to a http_transfer_encoding_t header structure, or NULL.

#define HTTPTAG_TRANSFER_ENCODING_STR

(

s

)

Tag list item for string with Transfer-Encoding header value.

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

Parameters:

s

pointer to a string containing http_transfer_encoding_t value, or NULL.

The HTTPTAG_TRANSFER_ENCODING_STR string can be converted to a http_transfer_encoding_t header structure by giving the string s has second argument to function http_transfer_encoding_make().

Enumeration Type Documentation

anonymous enum

Enumerator:

http_transfer_encoding_hash

Hash of Transfer-Encoding header.

Function Documentation

int http_is_transfer_encoding

(

http_header_t const *

header

)

[inline]

Test if header object is instance of http_transfer_encoding_t.

The function http_is_transfer_encoding() returns true (nonzero) if the header class is an instance of Transfer-Encoding header object and false (zero) otherwise.

Parameters:

header

pointer to the header structure to be tested

Returns:

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

http_transfer_encoding_t * http_transfer_encoding_copy	(	su_home_t *	home,
		http_transfer_encoding_t const *	hdr
	)			[inline]

Copy a http_transfer_encoding_t header structure.

The function http_transfer_encoding_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

   transfer_encoding = http_transfer_encoding_copy(home, http->http_transfer_encoding);

Returns:

The function http_transfer_encoding_copy() returns a pointer to newly copied header structure, or NULL upon an error.

http_transfer_encoding_t * http_transfer_encoding_dup	(	su_home_t *	home,
		http_transfer_encoding_t const *	hdr
	)			[inline]

Duplicate (deep copy) http_transfer_encoding_t.

The function http_transfer_encoding_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

   transfer_encoding = http_transfer_encoding_dup(home, http->http_transfer_encoding);

Returns:

The function http_transfer_encoding_dup() returns a pointer to the newly duplicated http_transfer_encoding_t header structure, or NULL upon an error.

http_transfer_encoding_t * http_transfer_encoding_format	(	su_home_t *	home,
		char const *	fmt,
			...
	)			[inline]

Make a Transfer-Encoding header from formatting result.

The function http_transfer_encoding_format() makes a new Transfer-Encoding 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_transfer_encoding_format() returns a pointer to newly makes header structure, or NULL upon an error.

http_transfer_encoding_t* http_transfer_encoding_init

(

http_transfer_encoding_t

x[1]

)

[inline]

Initialize a structure http_transfer_encoding_t.

An http_transfer_encoding_t structure can be initialized with the http_transfer_encoding_init() function/macro. For instance,

  http_transfer_encoding_t http_transfer_encoding;

  http_transfer_encoding_init(&http_transfer_encoding);

http_transfer_encoding_t * http_transfer_encoding_make	(	su_home_t *	home,
		char const *	s
	)			[inline]

Make a header structure http_transfer_encoding_t.

The function http_transfer_encoding_make() makes a new http_transfer_encoding_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_transfer_encoding_make() returns a pointer to newly maked http_transfer_encoding_t header structure, or NULL upon an error.

Variable Documentation

msg_hclass_t http_transfer_encoding_class[]

Header class for HTTP Transfer-Encoding header.

The header class http_transfer_encoding_class defines how a HTTP Transfer-Encoding header is parsed and printed. It also contains methods used by HTTP parser and other functions to manipulate the http_transfer_encoding_t header structure.
