HandleAllocated reflects the current state of Handle. the event is fired immediately or, if the component needs to cache the events, OnFocusedNode must be fired many times as the focused node was actually changed. Browse other questions tagged windows windbg resource-leak or ask your own question. TIdSocketHandle.Send TIdSocketHandle, See Also Sends data using a connected socket.
CloseSocket is affected by options used in SetSockOpt for Id_SO_LINGER. This allows the protocol stack to assign a unique port to the application with a value between 1024 and 5000. Id_SO_REUSEADDR - Boolean Allow the socket to be bound to an address which is already in use. optname: Integer Socket option to retrieve. find more info
PeerIP is updated in SetPeer, and as a result of Accept, SendTo, and RecvFrom operations. Join them; it only takes a minute: Sign up Where was handle allocated? Send returns the total number of bytes sent over the socket connection. If the socket is ready to read, no further processing is performed.
destructor Destroy; override; Description Destroy is the destructor for the collection item. Id_SO_RCVTIMEO - Data Integer Receive timeout. Use Accept to service a pending connection request. When Connect has successfully completed, the socket will be ready to send and receive data using Send, SendTo, Recv, and RecvFrom.
Declaring arrays in C++ What reason could change people's mentality to treat each other as members of one kind? Use HandleAllocated rather than reading the Handle property. You cannot edit other posts. const APort: Integer Port number of the remote system.
Readable does not yield processing cycles when an instance of TIdAntifreeze has not been used in the application. Discover More Id_IP_TTL - Data Integer Set Time-To-Live in IP header fields. Description Send is an Integer function used to write outgoing data to a connected socket. Listen is normally used in server applications that allow multiple simultaneous connections.
You cannot delete your own topics. procedure Reset(const AResetLocal: boolean = True); Parameters const AResetLocal: boolean = True Indicates that IP and Port are cleared for the connection. Return Value Integer - 0 on success. The data is copied into the read buffer, but is not removed from the input queue. TIdSocketHandle.RecvFrom TIdSocketHandle, See Also Receive data from a socket and store the remote system address.
This is pertinent to handle leak analysis. Readable returns True when the socket descriptor is ready for read operations using Recv, RecvFrom, or Accept. Assign updates the following property values: IP Port PeerIP PeerPort TIdSocketHandle.Bind TIdSocketHandle, See Also Associates a local address with a socket.

Return Value Integer - Number of bytes read.
It will change the focused node with the expression:tree.FocusedNode := ...Actual Results:OnFocusedNodeChanged does not fire until you activate the page which is its parent and, however, ONCE.Expected Results:If you set FocusedNode You cannot edit other events. procedure CloseSocket(const AResetLocal: boolean = True); virtual; Parameters const AResetLocal: boolean = True Clears the local IP address and Port number when True. Description SetSockOpt is a procedure used to set the value of socket-level options for a socket descriptor.
Default is Id_IPPROTO_IP. var VPort: Integer Port number of the remote connection.

Port numbers below 1024 are reserved, but using a number above 1024 does not guarantee there will be no conflict.
Connect uses IP and Port, and the parameter AFamily, to call the Connect facilities of the protocol stack. Reset clears the following properties to their uninitialized values: HandleAllocated - False Handle - Id_INVALID_SOCKET PeerIP - '' (empty string) PeerPort - 0 When aResetLocal is True, the IP and Port Accept is used by the listening thread of server applications that spawn new threads for each connection request, like TIdListenerThread and TIdUDPListenerThread. optval: PChar Value for the requested option.
property PeerIP: string; Description PeerIP is a read-only String property that identifies the address of the computer on the remote connection. Use SetSockOpt to update the options for a socket descriptor. procedure UpdateBindingLocal; Description UpdateBindingLocal is a procedure used to insure that the socket handle allocated for a connection uses the proper Protocol family, IP, and Port.

Readable detects the use of a TIdAntifreeze instance in an application. asked 7 years ago viewed 575 times active 7 years ago Related 3How to trace handle leaks?7What can cause section handle leaks?3native memory leak - how to find callstack of allocation Why would a crash landed generation fall back to the stone age? HandleAllocated is used to allow sockets, altered using SetSockOpt, to indicate that the socket handle is no longer available for send and receive operations.
Destroy will call CloseSocket prior to invoking the inherited Destroy destructor. Port is used in conjunction with IP to determine the local association used to identify the connection endpoint from Bind and Connect.
