Collaboration diagram for Content-Language Header:
![]() |
Note that this might not be equivalent to all the languages used within the entity-body. Its syntax is defined in RFC 3261 as follows:
Content-Language = "Content-Language" HCOLON language-tag *(COMMA language-tag) language-tag = primary-tag *( "-" subtag ) primary-tag = 1*8ALPHA subtag = 1*8ALPHA

Variables | |
tag_typedef_t | siptag_content_language |

tag_typedef_t | siptag_content_language_str |
Tag for string with Content-Language header value. | |
msg_hclass_t | sip_content_language_class [] |
Header class for SIP Content-Language header. |
#define SIP_CONTENT_LANGUAGE_INIT | ( | ) |
Initializer for structure sip_content_language_t.
A static sip_content_language_t structure must be initialized. The SIP_CONTENT_LANGUAGE_INIT() macro provides initialization value. For instance,
#define SIPTAG_CONTENT_LANGUAGE | ( | x | ) |
Tag list item for pointer to a Content-Language header structure.
The SIPTAG_CONTENT_LANGUAGE() macro is used to include a tag item with a pointer to a sip_content_language_t object in a tag list.
x | pointer to a sip_content_language_t header structure, or NULL. |
#define SIPTAG_CONTENT_LANGUAGE_STR | ( | s | ) |
Tag list item for string with Content-Language header value.
The SIPTAG_CONTENT_LANGUAGE_STR() macro is used to include a tag item with a string containing value of a sip_content_language_t header in a tag list.
s | pointer to a string containing sip_content_language_t value, or NULL. |
The corresponding tag taking reference parameter is SIPTAG_CONTENT_LANGUAGE_STR_REF().
typedef struct msg_content_language_s sip_content_language_t |
The structure sip_content_language_t contains representation of Content-Language header.
The sip_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 } sip_content_language_t;
sip_content_language_hash |
@
Hash of Content-Language header.
sip_content_language_t * sip_content_language_copy | ( | su_home_t * | home, | |
sip_content_language_t const * | hdr | |||
) | [inline] |
Copy a sip_content_language_t header structure.
The function sip_content_language_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.
home | memory home used to allocate new structure | |
hdr | pointer to the header structure to be copied |
content_language = sip_content_language_copy(home, sip->sip_content_language);
sip_content_language_t * sip_content_language_dup | ( | su_home_t * | home, | |
sip_content_language_t const * | hdr | |||
) | [inline] |
Duplicate (deep copy) sip_content_language_t
.
The function sip_content_language_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.
home | memory home used to allocate new structure | |
hdr | header structure to be duplicated |
content_language = sip_content_language_dup(home, sip->sip_content_language);
sip_content_language_t * sip_content_language_format | ( | su_home_t * | home, | |
char const * | fmt, | |||
... | ||||
) | [inline] |
Make a Content-Language header from formatting result.
The function sip_content_language_format() makes a new Content-Language 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.
home | memory home used to allocate new header structure. | |
fmt | string used as a printf()-style format | |
... | argument list for format |
sip_content_language_t* sip_content_language_init | ( | sip_content_language_t | x[1] | ) | [inline] |
Initialize a structure sip_content_language_t.
An sip_content_language_t structure can be initialized with the sip_content_language_init() function/macro. For instance,
sip_content_language_t sip_content_language; sip_content_language_init(&sip_content_language);
sip_content_language_t * sip_content_language_make | ( | su_home_t * | home, | |
char const * | s | |||
) | [inline] |
Make a header structure sip_content_language_t.
The function sip_content_language_make() makes a new sip_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 sip_is_content_language | ( | sip_header_t const * | header | ) | [inline] |
Test if header object is instance of sip_content_language_t.
The function sip_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 SIP Content-Language header.
The header class sip_content_language_class defines how a SIP Content-Language header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_content_language_t header structure.
