Creating an explicitly bound -socket

Explicitly bound sockets can be created in two ways:

- -Open a socket and bind the socket to a network interface connection. -
    -

  • Call RSocket::Open() and pass an RConnection.

    RConnection binds -to an interface corresponding to the RConnection.

    -In the following example code, if iConn corresponds to a -WiFi RConnection then, after a calling RSocket::Open() the -socket is explicitly bound to WiFi.

-Explicit binding example

Client A creates a socket -with explicit binding using the specified interface connection.

sock1 = RSocket.Open(srv,conn);

ESock -creates the socket within the default connection and subconnection.

A socket can also be opened over a sub-connection using RSubConnection. -When the socket is opened, a new Service Access Point (SAP) is created for -the socket in ESock. The SAP is used to handle inbound -and outbound data.
