SYNOPSIS
        #include <sys/driver_hooks.h>

        set_driver_hook(H_DEFAULT_METHOD, value)

        <value> being:

          int <name>(mixed & result, string fun, varargs args)
          int <closure>(mixed & result, object ob, string fun, varargs args)

DESCRIPTION
        Optional hook to provide default implementation for unresolved
        calls. Hook setting can be any closure, or the name of the
        function to call in the object.

        This hook is called whenever a call_other(), call_resolved(),
        call_strict() or call_out() on named function (as opposed to
        a closure) couldn't be resolved. The hook has then the
        opportunity to provide a default implementation.

        Exempt from this behaviour are calls to the master object, to
        simul-efuns, and calls done with call_direct(),
        call_direct_resolved() and call_strict_resolved().

        If the hook is the name of an lfun, it is called in the target
        object; otherwise if it is a closure, the target object is
        passed as parameter <ob>.

        The other parameters passed are the name <fun> of the called
        function, the arguments <args> passed to the call (if any),
        and a reference <result> to a variable for the call result.

        If the hook can resolve the call, it has to return the call
        result in <result> and 1 as function result.

        If the hook can not (or doesn't want to) resolve the call, it
        has to return 0.
