Boolean class_is_subtype	(	Class *	sub,
		Class *	super
	)

Runtime support functions exported directly, because they may be called from native code.

Boolean class_is_subtype_fast	(	VTable *	sub,
		Class *	super
	)

Like class_is_subtype, but sub must not be an interface class.

VMEXPORT void* vm_create_helper_for_function

(

void *(*)(void *)

fptr

)

Generates an VM's helper to invoke the provided function.

The helper takes the void* parameter, which is passed to the function after some preparation made (namely GC and stack info are prepared to allow GC to work properly).

The function must follow stdcall convention, which takes void* and returns void*, so does the helper. On a return from the function, the helper checks whether an exception was raised for the current thread, and rethrows it if necessary.
