C code cannot call Edebug since Edebug only applies to Lisp code.
As for calling `debug' there are various ways to do that, one of them is
to call the function stored in the variable `debugger', i.e.

  val = apply1 (Vdebugger, arg);

but it's usually not needed/desired (most of the time, the better
option is to signal an error, which can then in turn trigger the
debugger depending on debug-on-error and such).
