SpawnOptionsWithStdioTuple

The signal value to be used when the spawned process will be killed by the abort signal.

Specify the kind of serialization used for sending messages between processes.

Can be set to 'pipe', 'inherit', 'overlapped', or 'ignore', or an array of these strings. If passed as an array, the first element is used for stdin, the second for stdout, and the third for stderr. A fourth element can be used to specify the stdio behavior beyond the standard streams. See {@link ChildProcess.stdio} for more information.
