The Content-Disposition header field describes how the message body or, in the case of multipart messages, a message body part is to be interpreted by the UAC or UAS. Its syntax is defined in [S20.11] as follows:
Content-Disposition = "Content-Disposition" ":"
disposition-type *( ";" disposition-param )
disposition-type = "render" | "session" | "icon" | "alert"
| disp-extension-token
disposition-param = "handling" "="
( "optional" | "required" | other-handling )
| generic-param
other-handling = token
disp-extension-token = token
The Content-Disposition header was extended by draft-lennox-sip-reg-payload-01.txt section 3.1 as follows:
Content-Disposition = "Content-Disposition" ":"
disposition-type *( ";" disposition-param )
disposition-type /= "script" | "sip-cgi" | token
disposition-param /= action-param
/ modification-date-param
action-param = "action" "=" action-value
action-value = "store" | "remove" | token
modification-date-param = "modification-date" "=" quoted-date-time
quoted-date-time = <"> SIP-date <">
◆ MSG_CONTENT_DISPOSITION_INIT

| ) |
|
Initializer for an msg_content_disposition_t structure.
A static msg_content_disposition_t structure must be initialized with the MSG_CONTENT_DISPOSITION_INIT() macro. For instance,
#define MSG_CONTENT_DISPOSITION_INIT()
Initializer for an msg_content_disposition_t structure.
Definition msg_mime_protos.h:352
Structure for Content-Disposition header.
Definition msg_mime.h:106
◆ msg_content_disposition_t
The structure msg_content_disposition_t contains representation of an Content-Disposition header.
The msg_content_disposition_t is defined as follows:
{
struct msg_content_disposition_s msg_content_disposition_t
The structure msg_content_disposition_t contains representation of an Content-Disposition header.
Definition msg_mime.h:60
Common part of the header objects (or message fragments).
Definition msg_types.h:111
msg_common_t cd_common[1]

msg_content_disposition_hash | Hash of Content-Disposition header.

◆ msg_content_disposition_copy()
Copy an msg_content_disposition_t header structure.
The function msg_content_disposition_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.
- Parameters
-
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.
- Example
msg_content_disposition_t * msg_content_disposition_copy(su_home_t *home, msg_content_disposition_t const *header)
Copy an msg_content_disposition_t header structure.
Definition msg_mime_protos.h:481
- Returns
- The function msg_content_disposition_copy() returns a pointer to newly copied header structure, or NULL upon an error.
◆ msg_content_disposition_dup()
Duplicate (deep copy) msg_content_disposition_t.
The function msg_content_disposition_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.
- Parameters
-
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.
- Example
msg_content_disposition_t * msg_content_disposition_dup(su_home_t *home, msg_content_disposition_t const *header)
Duplicate (deep copy) msg_content_disposition_t.
Definition msg_mime_protos.h:436
- Returns
- The function msg_content_disposition_dup() returns a pointer to the newly duplicated msg_content_disposition_t header structure, or NULL upon an error.
◆ msg_content_disposition_format()
Make a Content-Disposition header from formatting result.
The function msg_content_disposition_format() makes a new Content-Disposition 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.
- Parameters
-
home | memory home used to allocate new header structure. |
fmt | string used as a printf()-style format |
... | argument list for format |
- Note
- This function may be implemented as a macro calling msg_header_format().
- Returns
- The function msg_content_disposition_format() returns a pointer to newly makes header structure, or NULL upon an error.

Test if header object is an instance of msg_content_disposition_t.
The function msg_is_content_disposition() returns true (nonzero) if the header class is an instance of Content-Disposition header object and false (zero) otherwise.
- Parameters
-
header | pointer to the header structure to be tested |
- Returns
- The function msg_is_content_disposition() returns true (nonzero) if the header object is an instance of header Content-Disposition header and false (zero) otherwise.
◆ msg_content_disposition_class
Header class for Content-Disposition header.
The header class msg_content_disposition_class defines how a Content-Disposition header header is parsed and printed. It also contains methods used by message parser and other functions to manipulate the msg_content_disposition_t header structure.
