Detailed Description

Defines a factory that actively connects to a remote IP address and TCP port, creating a new ACE_SOCK_Stream object.

The ACE_SOCK_Connector doesn't have a socket of its own, i.e., it simply "borrows" the one from the ACE_SOCK_Stream that's being connected. The reason for this is that the underlying socket API doesn't use a factory socket to connect data mode sockets. Therefore, there's no need to inherit ACE_SOCK_Connector from ACE_SOCK. A nice side-effect of this is that ACE_SOCK_Connector objects do not store state so they can be used reentrantly in multithreaded programs.

) 
 

Actively connect to a peer, producing a connected ACE_SOCK_Stream object if the connection succeeds.

Parameters:
new_stream The ACE_SOCK_Stream object that will be connected to the peer.
remote_sap The address that we are trying to connect to. The protocol family of remote_sap is used for the connected socket. That is, if remote_sap contains an IPv6 address, a socket with family PF_INET6 will be used, else it will be PF_INET.
timeout Pointer to an 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. If *timeout > {0, 0} then this is the maximum amount 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 attmpted that TCP times out - in the latter case, errno will be ETIMEDOUT.
local_sap (optional) The local address to bind to. If it's the default value of ACE_Addr::sap_any then the OS will choose an unused port.
reuse_addr (optional) If the value is 1, the local address (local_sap) is reused, even if it hasn't been cleaned up yet.
flags Ignored.
perms Ignored.
protocol (optional) If value is 0, default SOCK_STREAM protocol is selected by kernel (typically TCP).
Returns:
Returns 0 if the connection succeeds. If it fails, -1 is returned and errno contains a specific error code.
