The StartExternalProcess function starts an external process. The function returns false if no arguments are passed or if starting of the process fails.

• command: The command to execute.
• arguments: The arguments for the command.
• waitUntilFinished (since 1.0.1): If true then the function blocks until the process finishes. If false, then the function immediately returns.
• waitTimeoutMS (since 1.0.1): The timeout for the command.
• returnResultData (since 1.0.1): If true then the output of the command is returned as text.

(bool|string): StartExternalProcess(string command, [array arguments = [], bool waitUntilFinished = false, int waitTimeoutMS = 10000, bool returnResultData = false])

var result = StartExternalProcess();
// result: false

var result = StartExternalProcess('c:/test/test.exe');
// starts the external program "test.exe".

var args = ["A", "B"];
var result = StartExternalProcess('c:/test/test.exe', args);
// starts the external program with arguments "test.exe A B".

var args = ["A", "B"];
var result = StartExternalProcess('c:/test/test.exe', args, true, 10000, true);
// starts the external program with arguments "test.exe A B" and waits 10
// seconds. If the command succeeds then the result string is returned.
// If the command fails (or times out) then false is returned.
