TROBaseServerSocket

 

Creates a new instance.

constructor Create

---

procedure AbortSocket

---

Begins an asynchronous operation to accept an incoming connection attempt.

function Accept: THandle

---

Associates a socket with ip and port

procedure Bind(IP: string; Port: Word)

Parameters:

• IP: IP address to assign to this socket
• Port: Numeric value of the offered service

---

function CanRead(aTimeout: Integer): Boolean

Parameters:

• aTimeout:

---

procedure CloseSocket

---

procedure Connect(IP: string; Port: Word)

Parameters:

• IP:
• Port:

---

Creates OpenSSL properties

procedure CreateOpenSSL

---

procedure CreateSocket

---

procedure ExceptCheck(aRaiseExcept: Boolean; aAbortSocket: Boolean)

Parameters:

• aRaiseExcept:
• aAbortSocket:

---

function GetErrorDescEx: string

---

function GetLocalSinIP: string

---

function GetRemoteSinIP: string

---

Returns OpenSSL properties

function GetServerOpenSSL: TROServerSocketOpenSSL

---

procedure GetSins

---

function IsValidSocket: Boolean

---

property LastError: Integer read

---

property LastErrorDesc: string read

---

Establishes a socket to listen for an incoming connection.

procedure Listen(aBacklog: Integer = $7FFFFFFF)

Parameters:

• aBacklog: Desired maximum length of the queue of pending connections. This value may be changed by the transport layer.

---

property Mode: TROSocketMode read

---

Controls TCP packet batching (Nagle's algorithm).
TCP normally batches small logical packets into single larger physical packets (by briefly delaying packets) to fill physical network frames with as much data as possible. This is intended to improve network throughput in terminal emulation environments where mostly keystrokes are being sent across the network. Setting NoDelay to true disables TCP packet batching. Disabling TCP packet batching means that packets are sent regardless of size; this increases the volume of network traffic.

property NoDelay: Boolean read write

---

Specifies SSL properties

property OpenSSL: TROOpenSSL read

---

procedure OpenSSL_Connect

---

property PreferIP4: Boolean read write default True

---

property RaiseExcept: Boolean read write default True

---

function RecvBufferEx(Buffer: Pointer; Len: Integer; aTimeout: Integer = 0): Integer

Parameters:

• Buffer:
• Len:
• aTimeout:

procedure ResetLastError

---

Sends data to a connected Socket object.

function SendBuffer(Buffer: Pointer; Len: Integer): Boolean

Parameters:

• Buffer:

function SockCheck(SockResult: Integer = Integer(SOCKET_ERROR)): Integer

Parameters:

• SockResult:
