Data Structures
struct	actions

struct	mansession
	In case you didn't read that giant block of text above the mansession_session struct, the struct mansession is named this solely to keep the API the same in Asterisk. This structure really represents data that is different from Manager action to Manager action. The mansession_session pointer contained within points to session-specific data. More...

Descriptor for a manager session, either on the AMI socket or over HTTP.

Note

AMI session have managerid == 0; the entry is created upon a connect, and destroyed with the socket. HTTP sessions have managerid != 0, the value is used as a search key to lookup sessions (using the mansession_id cookie, or nonce key from Digest Authentication http header).

MSG_MOREDATA

#define MSG_MOREDATA   ((char *)astman_send_response)

Note

NOTE: XXX this comment is unclear and possibly wrong. Callers of astman_send_error(), astman_send_response() or astman_send_ack() must EITHER hold the session lock or be running in an action callback (in which case s->session->busy will be non-zero). In either of these cases, there is no need to lock-protect the session's fd, since no other output will be sent (events will be queued), and no input will be read until either the current action finishes or get_input() obtains the session lock.

Todo:

XXX MSG_MOREDATA should go to a header file.

__astman_get_header()

static const char* __astman_get_header ( const struct message *  m, char *  var, int  mode  )

static

Return a matching header value.

Generic function to return either the first or the last matching header from a list of variables, possibly skipping empty strings.

Note

At the moment there is only one use of this function in this file, so we make it static.

Never returns NULL.
