* PF_INET6 will be used, else it will be PF_INET.
* @note remote_sap must be an address on the local
* host.
* @param timeout Pointer to an @c ACE_Time_Value object with amount
* of time to wait to connect. If the pointer is 0
* then the call blocks until the connection attempt
* is complete, whether it succeeds or fails. If
* *timeout == {0, 0} then the connection is done
* using nonblocking mode. In this case, if the
* connection can't be made immediately, this method
* returns -1 and errno == EWOULDBLOCK.

* of time to wait before timing out; if the specified
* amount of time passes before the connection is made,
* this method returns -1 and errno == ETIME. Note
* the difference between this case and when a blocking
* connect is attempted that TCP times out - in the latter
* case, errno will be ETIMEDOUT.
* @param local_sap (optional) The local address to bind to. If it's
* the default value of @c ACE_Addr::sap_any then the
* OS will choose an unused port.
