syntax for calling a function from a DLL ?

[ffred]

Hi,
just tried to call functions from a DLL and used v translate -wrapper aiousb.h to generate a wrapper.
the syntax generated doesn't work and give me a "cannot call a function that does not have a body" error.
here is the simplest extracted sample code :

module main

#flag windows -laiousb

[c:'GetDevices']
fn getdevices() u32

fn main() {
	dev := getdevices()
	println('devices: "$dev"')
}

now if I do it this way (like I found on examples), it's ok :

module main

#flag windows -laiousb

fn C.GetDevices() u32

fn main() {
	dev := C.GetDevices()
	println('devices: "$dev"')
}

what should I do to use the syntax generated by v translate ?

[c:'GetDevices']
fn getdevices() u32
