| enum parse_sst_result parse_session_expires | ( | struct sip_msg * | msg, | |

| ) |
Parses the (should be only one instance) single instance of the "Session-Expires" or "x" header in the msg.
- Note:
- The header is not automatically parsed in parse_headers()[1] so you'll have to call this function to get the information.
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").
- Parameters:
-
msg the sip message to examine se the place to store session-expires information into, if provided; note that result is also available in *((struct session_expires *)msg->session_expires->parsed)
- Returns:
- parse_sst_result
