Header class for Content-Language header. |
The Content-Language header describes the natural language(s) of the intended audience for the enclosed message body.
Note that this might not be equivalent to all the languages used within the message-body. Its syntax is defined in [H14.12, S20.13] as follows:
Content-Language = "Content-Language" ":" 1#language-tag
or
Content-Language = "Content-Language" HCOLON language-tag *(COMMA language-tag) language-tag = primary-tag *( "-" subtag ) primary-tag = 1*8ALPHA subtag = 1*8ALPHA
#define MSG_CONTENT_LANGUAGE_INIT | ( | ) |
Initializer for an msg_content_language_t structure.
A static msg_content_language_t structure must be initialized with the MSG_CONTENT_LANGUAGE_INIT() macro. For instance,
msg_content_language_t msg_content_language = MSG_CONTENT_LANGUAGE_INIT;
typedef struct msg_content_language_s msg_content_language_t |
The structure msg_content_language_t contains representation of Content-Language header.
The msg_content_language_t is defined as follows:
typedef struct { msg_common_t k_common[1]; // Common fragment info msg_content_language_t *k_next; // (Content-Encoding header) msg_param_t *k_items; // List of languages } msg_content_language_t;
msg_content_language_t * msg_content_language_copy | ( | su_home_t * | home, | |
msg_content_language_t const * | header | |||
) | [inline] |
Copy an msg_content_language_t header structure.
The function msg_content_language_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.
content_language = msg_content_language_copy(home, msg->msg_content_language);
msg_content_language_t * msg_content_language_dup | ( | su_home_t * | home, | |
msg_content_language_t const * | header | |||
) | [inline] |
Duplicate (deep copy) msg_content_language_t.
The function msg_content_language_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.
content_language = msg_content_language_dup(home, msg->msg_content_language);
msg_content_language_t * msg_content_language_format | ( | su_home_t * | home, | |
char const * | fmt, | |||
... | ||||
) | [inline] |
Make a Content-Language header from formatting result.
The function msg_content_language_format() makes a new Content-Language 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_content_language_t* msg_content_language_init | ( | msg_content_language_t | x[1] | ) | [inline] |
Initialize an msg_content_language_t structure.
An msg_content_language_t structure can be initialized with the msg_content_language_init() function/macro. For instance,
msg_content_language_t msg_content_language; msg_content_language_init(&msg_content_language);
x | pointer to msg_content_language_t structure |
msg_content_language_t* msg_content_language_make | ( | su_home_t * | home, | |
char const * | s | |||
) | [inline] |
Make a header structure msg_content_language_t.
The function msg_content_language_make() makes a new msg_content_language_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_content_language | ( | msg_header_t const * | header | ) | [inline] |
Test if header object is an instance of msg_content_language_t.
The function msg_is_content_language() returns true (nonzero) if the header class is an instance of Content-Language header object and false (zero) otherwise.
header | pointer to the header structure to be tested |
Header class for Content-Language header.
The header class msg_content_language_class defines how a Content-Language header header is parsed and printed. It also contains methods used by message parser and other functions to manipulate the msg_content_language_t header structure.
