Variables | |
tag_typedef_t | siptag_content_type |
Tag for Content-Type header object. | |
tag_typedef_t | siptag_content_type_str |
Tag for string with Content-Type header value. | |
msg_hclass_t | sip_content_type_class [] |
Header class for SIP Content-Type header. |
#define SIP_CONTENT_TYPE_INIT | ( | ) |
Initializer for structure sip_content_type_t.
A static sip_content_type_t structure must be initialized. The SIP_CONTENT_TYPE_INIT() macro provides initialization value. For instance,
#define SIPTAG_CONTENT_TYPE | ( | x | ) |
Tag list item for pointer to a Content-Type header structure.
The SIPTAG_CONTENT_TYPE() macro is used to include a tag item with a pointer to a sip_content_type_t object in a tag list.
x | pointer to a sip_content_type_t header structure, or NULL. |
#define SIPTAG_CONTENT_TYPE_STR | ( | s | ) |
Tag list item for string with Content-Type header value.
The SIPTAG_CONTENT_TYPE_STR() macro is used to include a tag item with a string containing value of a sip_content_type_t header in a tag list.
s | pointer to a string containing sip_content_type_t value, or NULL. |
The corresponding tag taking reference parameter is SIPTAG_CONTENT_TYPE_STR_REF().
typedef struct sip_content_type_s sip_content_type_t |
The structure sip_content_type_t contains representation of SIP Content-Type header.
The sip_content_type_t is defined as follows:
typedef struct sip_content_type_s { sip_common_t c_common[1]; // Common fragment info sip_unknown_t *c_next; // Dummy link to next char const *c_type; // Pointer to type/subtype char const *c_subtype; // Points after first slash in type msg_param_t const *c_params; // List of parameters } sip_content_type_t;
The whitespace in the c_type is always removed when parsing.
sip_content_type_hash |
@
Hash of Content-Type header.
sip_content_type_t * sip_content_type_copy | ( | su_home_t * | home, | |
sip_content_type_t const * | hdr | |||
) | [inline] |
Copy a sip_content_type_t header structure.
The function sip_content_type_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_type = sip_content_type_copy(home, sip->sip_content_type);
sip_content_type_t * sip_content_type_dup | ( | su_home_t * | home, | |
sip_content_type_t const * | hdr | |||
) | [inline] |
Duplicate (deep copy) sip_content_type_t
.
The function sip_content_type_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_type = sip_content_type_dup(home, sip->sip_content_type);
sip_content_type_t * sip_content_type_format | ( | su_home_t * | home, | |
char const * | fmt, | |||
... | ||||
) | [inline] |
Make a Content-Type header from formatting result.
The function sip_content_type_format() makes a new Content-Type 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_type_t* sip_content_type_init | ( | sip_content_type_t | x[1] | ) | [inline] |
Initialize a structure sip_content_type_t.
An sip_content_type_t structure can be initialized with the sip_content_type_init() function/macro. For instance,
sip_content_type_t * sip_content_type_make | ( | su_home_t * | home, | |
char const * | s | |||
) | [inline] |
Make a header structure sip_content_type_t.
The function sip_content_type_make() makes a new sip_content_type_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_type | ( | sip_header_t const * | header | ) | [inline] |
Test if header object is instance of sip_content_type_t.
The function sip_is_content_type() returns true (nonzero) if the header class is an instance of Content-Type header object and false (zero) otherwise.
header | pointer to the header structure to be tested |
Header class for SIP Content-Type header.
The header class sip_content_type_class defines how a SIP Content-Type header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_content_type_t header structure.
