Variables | |
tag_typedef_t | siptag_content_encoding |

tag_typedef_t | siptag_content_encoding_str |
Tag for string with Content-Encoding header value. | |
msg_hclass_t | sip_content_encoding_class [] |
Header class for SIP Content-Encoding header. |
#define SIP_CONTENT_ENCODING_INIT | ( | ) |
Initializer for structure sip_content_encoding_t.
A static sip_content_encoding_t structure must be initialized. The SIP_CONTENT_ENCODING_INIT() macro provides initialization value. For instance,
#define SIPTAG_CONTENT_ENCODING | ( | x | ) |
Tag list item for pointer to a Content-Encoding header structure.
The SIPTAG_CONTENT_ENCODING() macro is used to include a tag item with a pointer to a sip_content_encoding_t object in a tag list.
x | pointer to a sip_content_encoding_t header structure, or NULL. |
#define SIPTAG_CONTENT_ENCODING_STR | ( | s | ) |
Tag list item for string with Content-Encoding header value.
The SIPTAG_CONTENT_ENCODING_STR() macro is used to include a tag item with a string containing value of a sip_content_encoding_t header in a tag list.
s | pointer to a string containing sip_content_encoding_t value, or NULL. |
The corresponding tag taking reference parameter is SIPTAG_CONTENT_ENCODING_STR_REF().
struct msg_list_s sip_content_encoding_t |
The structure sip_content_encoding_t contains representation of an Content-Encoding header.
The sip_content_encoding_t is defined as follows:
typedef struct msg_list_s { msg_common_t k_common[1]; // Common fragment info msg_list_t *k_next; // Link to next header msg_param_t *k_items; // List of items } sip_content_encoding_t;
sip_content_encoding_hash |
@
Hash of Content-Encoding header.
sip_content_encoding_t * sip_content_encoding_copy | ( | su_home_t * | home, | |
sip_content_encoding_t const * | hdr | |||
) | [inline] |
Copy a sip_content_encoding_t header structure.
The function sip_content_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.
home | memory home used to allocate new structure | |
hdr | pointer to the header structure to be copied |
content_encoding = sip_content_encoding_copy(home, sip->sip_content_encoding);
sip_content_encoding_t * sip_content_encoding_dup | ( | su_home_t * | home, | |
sip_content_encoding_t const * | hdr | |||
) | [inline] |
Duplicate (deep copy) sip_content_encoding_t
.
The function sip_content_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.
home | memory home used to allocate new structure | |
hdr | header structure to be duplicated |
content_encoding = sip_content_encoding_dup(home, sip->sip_content_encoding);
sip_content_encoding_t * sip_content_encoding_format | ( | su_home_t * | home, | |
char const * | fmt, | |||
... | ||||
) | [inline] |
Make a Content-Encoding header from formatting result.
The function sip_content_encoding_format() makes a new Content-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.
home | memory home used to allocate new header structure. | |
fmt | string used as a printf()-style format | |
... | argument list for format |
sip_content_encoding_t* sip_content_encoding_init | ( | sip_content_encoding_t | x[1] | ) | [inline] |
Initialize a structure sip_content_encoding_t.
An sip_content_encoding_t structure can be initialized with the sip_content_encoding_init() function/macro. For instance,
sip_content_encoding_t sip_content_encoding; sip_content_encoding_init(&sip_content_encoding);
sip_content_encoding_t * sip_content_encoding_make | ( | su_home_t * | home, | |
char const * | s | |||
) | [inline] |
Make a header structure sip_content_encoding_t.
The function sip_content_encoding_make() makes a new sip_content_encoding_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_encoding | ( | sip_header_t const * | header | ) | [inline] |
Test if header object is instance of sip_content_encoding_t.
The function sip_is_content_encoding() returns true (nonzero) if the header class is an instance of Content-Encoding header object and false (zero) otherwise.
header | pointer to the header structure to be tested |
Header class for SIP Content-Encoding header.
The header class sip_content_encoding_class defines how a SIP Content-Encoding header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_content_encoding_t header structure.
