This structure contains information for a connection request. The request attempts to make a connection to a plug control register on the local host.
hOutputPlugOn input, a handle to the output plug to use for the connection. If hOutputPlug is NULL, the connection is for input only.
hInputPlugOn input, handle to the input plug to use for the connection. If hInputPlug is NULL, the connection is for output only.
TypeOn input, the type of the requested connection.
The type of connection to make. Can be one of the following:
A broadcast connection.
