Functions

CreateUDPSocket

Function CreateUDPSocket:TSocket()

Description: Create a UDP socket

Returns: A new socket

Information: The new socket is not bound to any local or remote address.

CreateTCPSocket

Function CreateTCPSocket:TSocket()

Description: Create a TCP socket

Returns: A new socket

Information: The new socket is not bound to any local or remote address.

CloseSocket

Function CloseSocket( socket:TSocket )

Description: Close a socket

Information: All sockets should eventually be closed. Once closed, a socket can no longer be used.

BindSocket

Function BindSocket( socket:TSocket,localPort )

Description: Bind a socket to a local port

Returns: True if successful, otherwise false

Information: If localPort is 0, a new local port will be allocated. If localPort is not 0, BindSocket will fail if there is already an application bound to localPort.

ConnectSocket

Function ConnectSocket( socket:TSocket,remoteIp,remotePort )

Description: Connect a socket to a remote ip and port

Returns: True if successful, otherwise false

Information: For both UDP and TCP sockets, ConnectSocket will fail if the specified ip address could not be reached.

In the case of TCP sockets, ConnectSocket will also fail if there is no application listening at the remote port.

SocketListen

Function SocketListen( socket:TSocket,backlog=0 )

Description: Start listening at a socket

Information: The specified socket must be a TCP socket, and must already be bound to a local port.

SocketAccept

Function SocketAccept:TSocket( socket:TSocket,timeout=0 )

Description: Accept new connections on a listening socket

Returns: A new socket, or Null if no connection was made in the specified timeout

Information: The specified socket must be a TCP socket, and must be listening.

SocketConnected

Function SocketConnected( socket:TSocket )

Description: Get socket connection status

Returns: True if socket is connected

Information: SocketConnected allows you to determine if a TCP connection is still alive or has been remotely closed.

SocketConnected should only be used with TCP sockets that have already connected via ConnectSocket or SocketAccept.

SocketReadAvail

Function SocketReadAvail( socket:TSocket )

Description: Get number of bytes available for reading from a socket

Returns: Number of bytes that may be read without causing the socket to block

SocketLocalIP

Function SocketLocalIP( socket:TSocket )

Description: Get local ip of a socket

SocketLocalPort

Function SocketLocalPort( socket:TSocket )

Description: Get local port of a socket

SocketRemoteIP

Function SocketRemoteIP( socket:TSocket )

Description: Get remote ip of a socket

SocketRemotePort

Function SocketRemotePort( socket:TSocket )

Description: Get remote port of a socket

DottedIP

Function DottedIP$( ip )

Description: Convert an ip address to a dotted string

Returns: Dotted string version of ip address

HostIp

Function HostIp( HostName$,index=0 )

Description: Convert a host name to an ip address

Returns: Host ip address, or 0 if host not found

HostIps

Function HostIps:Int[]( HostName$ )

Description: Get all ip addresses for a host name

Returns: Array of host ips, or Null if host not found

HostName

Function HostName$( HostIp )

Description: Convert a host ip address to a name

Returns: Name of host, or Null if host not found
