Description Listen is a procedure that allows a bound socket descriptor to wait for incoming connections. You cannot vote within polls. SendTo is used on datagram or stream sockets. To send a broadcast datagram, the IP address parameter must contain Id_INADDR_ANY.

There are two types of socket options: Boolean and Data. Some protocols use pre-defined port numbers. property Port: integer; Description Port is an Integer property that identifies the port number on the local system where data is sent and received.

Select calls the TIdStack.WSSelect method to access the protocol stack routines that implements the select operation. CloseSocket is affected by options used in SetSockOpt for Id_SO_LINGER. Readable returns True when the socket descriptor is ready for read operations using Recv, RecvFrom, or Accept.

procedure Assign(Source: TPersistent); override; Parameters Source: TPersistent The object instance containing the values to copy. HandleAllocated is set to False to indicate to that the socket is no longer available to other threads of execution. Description RecvFrom is an Integer function used to read incoming data from a socket connection, and to store the address of the remote system in the variable parameters VIP and VPort. AResetLocal indicates that rest should be called for the local connection.

Recv is used on streaming sockets, to read all available data up to the size of the read buffer. PeerIP is updated in SetPeer, and as a result of Accept, SendTo, and RecvFrom operations.

HandleAllocated is used to allow sockets, altered using SetSockOpt, to indicate that the socket handle is no longer available for send and receive operations. Note: Many port numbers are associated, by convention, with a particular service such as ftp or http as described in IdPorts. Created with Doc-O-Matic 2 donated to Project JEDI.
