The kernel will respond to the bootstrap task (task 1) with the
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>.
Only generic errors apply.
