Header class for Accept-Charset header. |
The Accept-Charset header is similar to Accept, but restricts the character set that are acceptable in the response.
Its syntax is defined in [H14.2] as follows:
Accept-Charset = "Accept-Charset" ":" 1#( ( charset | "*" )[ ";" "q" "=" qvalue ] )
#define MSG_ACCEPT_CHARSET_INIT | ( | ) |
Initializer for an msg_accept_charset_t structure.
A static msg_accept_charset_t structure must be initialized with the MSG_ACCEPT_CHARSET_INIT() macro. For instance,
msg_accept_charset_t msg_accept_charset = MSG_ACCEPT_CHARSET_INIT;
typedef struct msg_accept_charset_s msg_accept_charset_t |
The structure msg_accept_encoding_t contains representation of Accept-Charset header.
The msg_accept_charset_t is defined as follows:
typedef struct { msg_common_t aa_common[1]; // Common fragment info msg_accept_any_t *aa_next; // Pointer to next Accept-Charset char const *aa_value; // Charset msg_param_t const *aa_params; // Parameter list char const *aa_q; // Q-value } msg_accept_charset_t;
msg_accept_charset_t * msg_accept_charset_copy | ( | su_home_t * | home, | |
msg_accept_charset_t const * | header | |||
) | [inline] |
Copy an msg_accept_charset_t header structure.
The function msg_accept_charset_copy() copies a header structure header. If the header structure header contains a reference (header->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 header.
home | memory home used to allocate new structure | |
header | 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.
accept_charset = msg_accept_charset_copy(home, msg->msg_accept_charset);
msg_accept_charset_t * msg_accept_charset_dup | ( | su_home_t * | home, | |
msg_accept_charset_t const * | header | |||
) | [inline] |
Duplicate (deep copy) msg_accept_charset_t.
The function msg_accept_charset_dup() duplicates a header structure header. If the header structure header contains a reference (header->x_next
) to a list of headers, all the headers in the list are duplicated, too.
home | memory home used to allocate new structure | |
header | 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.
accept_charset = msg_accept_charset_dup(home, msg->msg_accept_charset);
msg_accept_charset_t * msg_accept_charset_format | ( | su_home_t * | home, | |
char const * | fmt, | |||
... | ||||
) | [inline] |
Make a Accept-Charset header from formatting result.
The function msg_accept_charset_format() makes a new Accept-Charset header object using snprintf-formatted 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.
home | memory home used to allocate new header structure. | |
fmt | string used as a printf()-style format | |
... | argument list for format |
msg_accept_charset_t* msg_accept_charset_init | ( | msg_accept_charset_t | x[1] | ) | [inline] |
Initialize an msg_accept_charset_t structure.
An msg_accept_charset_t structure can be initialized with the msg_accept_charset_init() function/macro. For instance,
msg_accept_charset_t msg_accept_charset; msg_accept_charset_init(&msg_accept_charset);
x | pointer to msg_accept_charset_t structure |
msg_accept_charset_t* msg_accept_charset_make | ( | su_home_t * | home, | |
char const * | s | |||
) | [inline] |
Make a header structure msg_accept_charset_t.
The function msg_accept_charset_make() makes a new msg_accept_charset_t header structure. It allocates a new header structure, and decodes the string s as the value of the structure.
home | memory home used to allocate new header structure. | |
s | string to be decoded as value of the new header structure |
int msg_is_accept_charset | ( | msg_header_t const * | header | ) | [inline] |
Test if header object is an instance of msg_accept_charset_t.
The function msg_is_accept_charset() returns true (nonzero) if the header class is an instance of Accept-Charset header object and false (zero) otherwise.
header | pointer to the header structure to be tested |
Header class for Accept-Charset header.
The header class msg_accept_charset_class defines how a Accept-Charset header header is parsed and printed. It also contains methods used by message parser and other functions to manipulate the msg_accept_charset_t header structure.
