Actively connect and produce a <new_stream> if things go well. The <remote_sap> is the address that we are trying to connect with. The <timeout> is the amount of time to wait to connect. If it's 0 then we block indefinitely. If *timeout == {0, 0} then the connection is done using non-blocking mode. In this case, if the connection can't be made immediately the value of -1 is returned with <errno == EWOULDBLOCK>. If *timeout > {0, 0} then this is the amount of time to wait before timing out. If the time expires before the connection is made <errno == ETIME>. The <local_sap> is the value of local address to bind to. If it's the default value of <ACE_Addr::sap_any> then the user is letting the OS do the binding. If <reuse_addr> == 1 then the <local_addr> is reused, even if it hasn't been cleanedup yet.

const ACE_Addr &    remote_sap,
ACE_INT32    leaf_id,
ACE_Time_Value *    timeout = 0
) 
 

Actively add a leaf to the currently connected stream (i.e., multicast). The <remote_sap> is the address of the leaf that we are trying to add. The <timeout> is the amount of time to wait to connect. If it's 0 then we block indefinitely. If *timeout == {0, 0} then the connection is done using non-blocking mode. In this case, if the connection can't be made immediately the value of -1 is returned with <errno == EWOULDBLOCK>. If *timeout > {0, 0} then this is the amount of time to wait before timing out. If the time expires before the connection is made <errno == ETIME>.
