arguments and environment specified to the boot loader. The bootstrap

task can act as a server on this interface for the tasks that it

creates in order to pass arguments to them. The <strong>libsa_mach.a</strong>

standalone Mach C runtime startup code uses <strong>bootstrap_arguments</strong> and

<strong>bootstrap_environment</strong> to initialize <var>argc</var>, <var>argv</var>,

and <var>envp</var> for <strong>main</strong>.

<h3>RETURN VALUES</h3>

Only generic errors apply.
