api-table clj

close clj/s macro

(close socket-id)

Closes the socket and releases the address/port the socket is bound to. Each socket created should be closed after use. The socket id is no no longer valid as soon at the function is called. However, the socket is guaranteed to be closed only when the callback is invoked.

|socket-id| - The socket identifier.

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 [].

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.

https://developer.chrome.com/apps/sockets.tcp#method-close.

(close* config socket-id)

connect clj/s macro

(connect socket-id peer-address peer-port)

Connects the socket to a remote machine. When the connect operation completes successfully, onReceive events are raised when data is received from the peer. If a network error occurs while the runtime is receiving packets, a onReceiveError event is raised, at which point no more onReceive event will be raised for this socket until the resume method is called.

|socket-id| - The socket identifier. |peer-address| - The address of the remote machine. DNS name, IPv4 and IPv6 formats are supported. |peer-port| - The port of the remote machine.

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 [result] where:

|result| - The result code returned from the underlying network call. A negative value indicates an error.

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.
