Data Structures

struct session_expires
We will treat the 'void* parsed' field of struct hdr_field as a pointer to a struct session_expires. More...

Enumerations

enum sst_refresher
Indicate the "refresher=" value of the Session-Expires header.

Functions

void free_session_expires (struct session_expires *)
Deallocates memory previously allocated via malloc_session_expires().
struct session_expires * malloc_session_expires (void)
Allocate a zeroed-out struct session_expires.
enum parse_sst_result parse_min_se (struct sip_msg *msg, unsigned *min_se)
Parses the (should be only one instance) single instance of the "Min-SE" header in the msg.
enum parse_sst_result parse_session_expires (struct sip_msg *msg, struct session_expires *se)
Parses the (should be only one instance) single instance of the "Session-Expires" or "x" header in the msg.

Detailed Description

Function Documentation

enum parse_sst_result parse_min_se	(	struct sip_msg *	msg,
		unsigned *	min_se
	)

Note:: The header is not automatically parsed in parse_headers() so you'll have to call this function to get the information.

Parameters:

	msg	the sip message to examine
	min_se	the place to store the Min-SE value, if provided; note that result is also available in (unsigned)msg->min_se->parsed

Returns:: parse_sst_result

Referenced by parse_msg_for_sst_info(), and sst_check_min().

Here is the caller graph for this function:

enum parse_sst_result parse_session_expires	(	struct sip_msg *	msg,
		struct session_expires *	se
	)

Note:: The header is not automatically parsed in parse_headers()[1] so you'll have to call this function to get the information.

Because of time constraints, this function is coded assuming there is NO WHITESPACE in any of the body -- note that the augBNF for the Session-Expires body allows sep whitespace between tokens: delta-seconds SWS ";" SWS "refresher" SWS "=" SWS ( "uac" / "uas" )

Note[1]: it looks like only the frequently-used headers are automatically parsed in parse_headers() (indicated by a parse_<name> function of the form "char* parse_<name>(char *buf, char *end, foo*) and a struct foo with a member called "error").
