TInternetSocket.Create¶

function TInternetSocket.Create(AHost: String; APort: UInt16; UseSSL: Boolean): TInternetSocket; static;

Basic internet socket functionality. The socket is blocking which means Read calls will wait for data to arrive.

Use either ReadWriteTimeout() / HasData() / ReadStringUntil() to avoid hanging.

TInternetSocket.Connect¶

procedure TInternetSocket.Connect;

Connects to the host and port.

TInternetSocket.Close¶

procedure TInternetSocket.Close;

Closes the socket

TInternetSocket.HasData¶

function TInternetSocket.HasData: Boolean;

Returns true if there is data waiting to be read.

TInternetSocket.Read¶

function TInternetSocket.Read(MaxLen: Integer = 8192): TByteArray;

Read bytes from the socket up to MaxLen bytes.

Note

By default this call is blocking - it will wait until there is data to be read. To change this behavior use ReadWriteTimeout or use HasData.

TInternetSocket.ReadUntil¶

function TInternetSocket.ReadUntil(Seq: TByteArray; Timeout: Integer): TByteArray;

Reads until the data ends with Seq or Timeout (in milliseconds) is reached. This is useful if you are reading data which is terminated with consistent endings.

TInternetSocket.ReadString¶

function TInternetSocket.ReadString(MaxLen: Integer = 8192): String;

ReadString a string from the socket up to MaxLen bytes.

TInternetSocket.ReadStringUntil¶

function TInternetSocket.ReadStringUntil(Seq: String; Timeout: Integer): String;

Reads a string until the data ends with Seq or Timeout (in milliseconds) is reached. This is useful if you are ReadStringing data which is terminated with consistent endings.

TInternetSocket.Write¶

function TInternetSocket.Write(Data: TByteArray): Integer;

Write bytes to the socket.

TInternetSocket.WriteString¶

function TInternetSocket.WriteString(Str: String): Integer;

Write a string to the socket.

TInternetSocket.LocalAddress¶

property TInternetSocket.LocalAddress: String;
