interfacing the C function so that Lisp can call it are handled by a few
C macros. The only way to really understand how to write new C code is
to read the source, but we can explain some things here.

Note that C code cannot call functions by name unless they are defined

@code{Ffuncall}, which embodies the Lisp function @code{funcall}. Since
the Lisp function @code{funcall} accepts an unlimited number of
arguments, in C it takes two: the number of Lisp-level arguments, and a
