Execute

Syntax

Execute(command, timeout, input, output);

command	The command to execute.
timeout	Timeout in seconds. StreamServer will wait the specified amount of time before it tries to shutdown the called process and returns to operation. Timeout set to -1 means StreamServer will “wait forever”. This is the default value.
input	Input data to send to the called process.
output	Array of three output variables: • output[0] – STDOUT output from the called process. • output[1] – STDERR output from the called process. • output[2] – Exit code from the called process.

Description

This script function executes an external program, script, bat file or process.

Note:

This script function has the same security context as the one defined for the StreamServer application (Log on setting defined for the StreamServer application). For example, if Log on as: Local System account is defined for the StreamServer application, this script function can only be executed on the local computer.

Returns

	OK.
	Command not found.
	Timeout reached.
	Maximum number of spawned process reached.
	Other error.
