Define Documentation

#define HTTP_ACCEPT_RANGES_INIT

(

)

Initializer for structure http_accept_ranges_t.

A static http_accept_ranges_t structure must be initialized with the HTTP_ACCEPT_RANGES_INIT() macro. For instance,

  http_accept_ranges_t http_accept_ranges = HTTP_ACCEPT_RANGES_INIT;

#define HTTPTAG_ACCEPT_RANGES

(

x

)

Tag list item for pointer to a Accept-Ranges header object.

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

Parameters:

x

pointer to a http_accept_ranges_t header structure, or NULL.

#define HTTPTAG_ACCEPT_RANGES_STR

(

s

)

Tag list item for string with Accept-Ranges header value.

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

Parameters:

s

pointer to a string containing http_accept_ranges_t value, or NULL.

The HTTPTAG_ACCEPT_RANGES_STR string can be converted to a http_accept_ranges_t header structure by giving the string s has second argument to function http_accept_ranges_make().

Function Documentation

http_accept_ranges_t * http_accept_ranges_copy	(	su_home_t *	home,
		http_accept_ranges_t const *	hdr
	)			[inline]

Copy a http_accept_ranges_t header structure.

The function http_accept_ranges_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

   accept_ranges = http_accept_ranges_copy(home, http->http_accept_ranges);

Returns:

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

http_accept_ranges_t * http_accept_ranges_dup	(	su_home_t *	home,
		http_accept_ranges_t const *	hdr
	)			[inline]

Duplicate (deep copy) http_accept_ranges_t.

The function http_accept_ranges_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

   accept_ranges = http_accept_ranges_dup(home, http->http_accept_ranges);

Returns:

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

http_accept_ranges_t * http_accept_ranges_format	(	su_home_t *	home,
		char const *	fmt,
			...
	)			[inline]

Make a Accept-Ranges header from formatting result.

The function http_accept_ranges_format() makes a new Accept-Ranges 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_accept_ranges_format() returns a pointer to newly makes header structure, or NULL upon an error.

http_accept_ranges_t* http_accept_ranges_init

(

http_accept_ranges_t

x[1]

)

[inline]

Initialize a structure http_accept_ranges_t.

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

  http_accept_ranges_t http_accept_ranges;

  http_accept_ranges_init(&http_accept_ranges);

http_accept_ranges_t * http_accept_ranges_make	(	su_home_t *	home,
		char const *	s
	)			[inline]

Make a header structure http_accept_ranges_t.

The function http_accept_ranges_make() makes a new http_accept_ranges_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_accept_ranges_make() returns a pointer to newly maked http_accept_ranges_t header structure, or NULL upon an error.

int http_is_accept_ranges

(

http_header_t const *

header

)

[inline]

Test if header object is instance of http_accept_ranges_t.

The function http_is_accept_ranges() returns true (nonzero) if the header class is an instance of Accept-Ranges header object and false (zero) otherwise.

Parameters:

header

pointer to the header structure to be tested

Returns:

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

Variable Documentation

msg_hclass_t http_accept_ranges_class[]

Header class for HTTP Accept-Ranges header.

The header class http_accept_ranges_class defines how a HTTP Accept-Ranges header is parsed and printed. It also contains methods used by HTTP parser and other functions to manipulate the http_accept_ranges_t header structure.
