26 /* These functions are an interface to the Lisp call-in facility.
27 * Since this is C we can know nothing about the calling environment.
28 * The control stack might be the C stack if called from the monitor
29 * or the Lisp stack if called as a result of an interrupt or maybe
30 * even a separate stack. The args are most likely on that stack but
31 * could be in registers depending on what the compiler likes. So we
32 * copy the args into a portable vector and let the assembly language
33 * call-in function figure it out. */
