void CloseAllConnections ( void )

@ brief close all open connections.

For I/O connections the sockets will be freed. The sockets for explicit connections are handled by the encapsulation layer, and freed there.

void CloseAllConnectionsForInputWithSameType	(	const EipUint32	input_point,
		const ConnectionObjectInstanceType	instance_type
	)

Close all connection producing the same input and have the same type (i.e., listen only or input only).

Parameters

input_point	the input point
instance_type	the connection application type

bool ConnectionWithSameConfigPointExists ( const EipUint32 config_point )

Check if there is an established connection that uses the same config point.

Parameters

config_point The configuration point

Returns: true if connection was found, otherwise false

CipConnectionObject* GetExistingProducerMulticastConnection ( const EipUint32 input_point )

Check if there exists already an exclusive owner or listen only connection which produces the input assembly.

Parameters

input_point the Input point to be produced

Returns: if a connection could be found a pointer to this connection if not NULL

Here is the caller graph for this function:

CipConnectionObject* GetIoConnectionForConnectionData	(	CipConnectionObject *const RESTRICT	connection_object,
		EipUint16 *const	extended_error
	)

check if for the given connection data received in a forward_open request a suitable connection is available.

If a suitable connection is found the connection data is transfered the application connection type is set (i.e., EConnType).

Parameters

connection_object	connection data to be used
extended_error	pointer to the extended_error variable, if an error occurred this value has the according error code for the response

Returns

on success: A pointer to the connection object already containing the connection data given in connection_object.
on error: NULL

Parameters

input_point the produced input
