clj

Use the chrome.socket API to send and receive data over the network using TCP and UDP connections. Note: Starting with Chrome 33, this API is deprecated in favor of the 'sockets.udp', 'sockets.tcp' and 'sockets.tcpServer' APIs.

accept clj/s macro

(accept socket-id)

This method applies to TCP sockets only. Registers a callback function to be called when a connection is accepted on this listening server socket. Listen must be called first. If there is already an active accept callback, this callback will be invoked immediately with an error as the resultCode.

|socket-id| - The socketId.

This function returns a core.async channel of type promise-chan which eventually receives a result value. Signature of the result value put on the channel is [accept-info] where:

In case of an error the channel closes without receiving any value and relevant error object can be obtained via chromex.error/get-last-error.

On Windows, the applications with loopback off will not RECEIVE the loopback packets; while on Unix-like systems, the applications with loopback off will not SEND the loopback packets to other applications on the same host.
