D.15.17.5 parallelTestOR

Usage:

parallelTestOR(commands, arguments[, timeout]); commands list or string, arguments list, timeout int

Return:

1, if commands[i] applied to arguments[i] is not equal to zero for any i = 1, ..., size(arguments);
0, otherwise.
An optional timeout in ms can be provided. Default is 0 which disables the timeout. In case of timeout, -1 is returned.

Note:

The entries of the list commands must be strings. The entries of the list arguments must be lists.
commands[i] applied to arguments[i] must evaluate to an integer for i = 1, ..., size(arguments).
As a shortcut, commands can be a string. This is synonymous to providing a list of size(arguments) copies of this string.

// test if any of the arguments has non-zero size
parallelTestOR(command, arguments1);
==> 1
parallelTestOR(command, arguments2);
==> 0
