SocketWaitAll

SocketWaitAll[{socket1,socket2,…}]

waits until there is data ready to read on all of the socketi.

Details

Examples

open all close all

Basic Examples  (2)

Connect to a site 5 times and measure how long it takes for all connections to be ready:

Wolfram Language code: clients = Table[SocketConnect["http://exampledata.wolfram.com"], 5];

Write a request out on all the sockets and measure how long it takes for all of them to get back a request:

Wolfram Language code: WriteString[#, "GET /50states.txt HTTP/1.1 "]& /@ clients; First@AbsoluteTiming[SocketWaitAll[clients]]

Close the sockets:

Wolfram Language code: Close /@ clients;

Open a server socket and connect some clients to it:

Wolfram Language code: server = SocketOpen[Automatic]; clients = Table[SocketConnect[server], 5];

Initially, none of the clients are ready:

Wolfram Language code: SocketReadyQ /@ clients

Write data to each of the clients from the server in the local session after a delay:

Wolfram Language code: SessionSubmit[ScheduledTask[WriteString[#, DateString[]], {5}]]& /@ server["ConnectedClients"];

Read the data sent to the clients once it has been submitted:

Wolfram Language code: AbsoluteTiming[SocketWaitAll[clients];ByteArrayToString /@ SocketReadMessage /@ clients]

Possible Issues  (1)

SocketWaitAll does not support web sockets:

Wolfram Language code: socket = SocketConnect["wss://echo.websocket.org"]; SocketWaitAll[{socket}]
