Typedef Documentation

typedef struct tibeftlConnectionStruct* tibeftlConnection

eFTL connection.

A tibeftlConnection object represents the connection to the server.

typedef struct tibeftlErrStruct* tibeftlErr

err	The connection error.
arg	The callback-specific argument.

See also: tibeftl_Connect

typedef struct tibeftlMessageStruct* tibeftlMessage

A tibeftlMessage object is used to send information between clients.

typedef void(* tibeftlMessageCallback) (tibeftlConnection conn, tibeftlSubscription sub, int cnt, tibeftlMessage *msg, void *arg)

Message callback.

A message callback is invoked whenever messages are received that matche a subscription.

Parameters

conn	The connection on which the message was received.
sub	The subscription associated with the message.
cnt	The number of received messages.
msg	The array of received messages.
arg	The callback-specific argument.

DLL_EXPORT tibeftlConnection tibeftl_Connect	(	tibeftlErr	err,
		const char *	url,
		tibeftlOptions *	opts,
		tibeftlErrorCallback	errCb,
		void *	errCbArg
	)

Connect to the server.

Creates a connection to the server.

The server URL has the syntax:

ws://host:port/channel wss://host:port/channel

Optionally, the URL can contain the username, password, and/or client identifier:

ws://username:password:port/channel?clientId=<identifier> wss://username:password:port/channel?clientId=<identifier>

Parameters

err	An eFTL error to capture information about failures.
url	The URL of the server.
opts	(optional) The options to use when creating the connection.
errCb	(optional) The error callback to be invoked when connection errors occur.

DLL_EXPORT void tibeftl_Disconnect	(	tibeftlErr	err,
		tibeftlConnection	conn
	)

Disconnect from the server and free all resources associated with the connection.

Parameters

err	An eFTL error to capture information about failures.
conn	The connection object.

DLL_EXPORT bool tibeftl_IsConnected	(	tibeftlErr	err,
		tibeftlConnection	conn
	)

Check whether or not there is a connection to the server.

Parameters

err	An eFTL error to capture information about failures.
conn	The connection object.

Returns: true if there is a connection to the server, false otherwise.

DLL_EXPORT void tibeftl_Publish	(	tibeftlErr	err,
		tibeftlConnection	conn,
		tibeftlMessage	msg
	)

Publish a message to all subscribing clients.

It is good practice to direct messages to specific destinations by adding a message string field with the name TIBEFTL_FIELD_NAME_DESTINATION.; for example:

1 tibeftlMessage_SetString(err, msg, TIBEFTL_FIELD_NAME_DESTINATION, "MyDest");

Parameters

err	An eFTL error to capture information about failures.

All subscriptions are restored following a successful reconnect.

Parameters

err	An eFTL error to capture information about failures.
conn	The connection object.

DLL_EXPORT tibeftlSubscription tibeftl_Subscribe	(	tibeftlErr	err,
		tibeftlConnection	conn,
		const char *	matcher,
		const char *	durable,
		tibeftlMessageCallback	msgCb,
		void *	msgCbArg
	)

Subscribe to messages.

A subscription can be narrowed by using a matcher that matches only those messages whose content is of interest.

It is good practice to subscribe to messages published to specific destinations by using the message field name TIBEFTL_FIELD_NAME_DESTINATION in the matcher; for example:

 char matcher[64];
 
 snprintf(matcher, sizeof(matcher), "{\"%s\":\"%s\"}",
         TIBEFTL_FIELD_NAME_DESTINATION, "MyDestination");
 
 tibeftl_Subscribe(err, conn, matcher, "MyDurable", cb, NULL);

Parameters

err	An eFTL error to capture information about failures.
conn	The connection object.
matcher	(optional) The matcher for selecting which messages to receive.
durable	(optional) The name to use when creating durable subscriptions.
msgCb	The message callback to be invoked when messages are received.
msgCbArg	The message callback argument.

DLL_EXPORT tibeftlSubscription tibeftl_SubscribeWithOptions	(	tibeftlErr	err,
