Subprocess

Description:

protected Subprocess ()

Create a new process with the given flags and varargs argument list.

By default, matching the spawn_async defaults, the child's stdin will be set to the system null device, and stdout/stderr will be inherited from the parent. You can use flags to control this behavior.

The argument list must be terminated with null.

Parameters:

argv0	first commandline argument to pass to the subprocess
error	return location for an error, or null
flags	flags that define the behaviour of the subprocess
...	more commandline arguments, followed by null

Returns:

A newly created Subprocess, or null on error (and error will be set)
