Why anyone would want to do this is beyond me, but here you go:

aFunction := ExternalLibraryFunction
	module: 'user32'
	callType: ExternalFunction callTypeAPI
	returnType: ExternalType bool
	argumentTypes: {
		ExternalType char asPointerType.
		ExternalType uint32
aFunction invokeWith: address with: 0.
