Cannot return 'void' from single line function

[ghost]

func DW_PIXMAP_WIDTH(x HPIXMAP) = (x ? x.width : 0)
func DW_PIXMAP_HEIGHT(x HPIXMAP) = (x ? x.height : 0)

HPIXMAP is a struct:

struct HPIXMAP (
    width ulong,
    height ulong,
    hbm HBITMAP,
    hdc HDC,
    transcolor ulong,
    handle HWND,
    bits ptr,
    depth ulong,
    font HFONT
)

This is because the function is missing a return type,

func DW_PIXMAP_WIDTH(x HPIXMAP) ulong = (x ? x.width : 0)
func DW_PIXMAP_HEIGHT(x HPIXMAP) ulong = (x ? x.height : 0)

@iahung2 It looks like this macro is supposed to operate on a pointer?

It's complaining that the x part of the ternary is not a boolean. So maybe

func DW_PIXMAP_WIDTH(x *HPIXMAP) ulong = (x ? x.width : 0)
func DW_PIXMAP_HEIGHT(x *HPIXMAP) ulong = (x ? x.height : 0)

is a better translation?

I decided to remove these functions. They are converted from macros and in my opinion they are not really needed.

[IsaacShelton]

The reason for that error was that the two branches of the ternary have to give the same type, so

func DW_PIXMAP_WIDTH(x *HPIXMAP) ulong = x ? x.width : 0ul
func DW_PIXMAP_HEIGHT(x *HPIXMAP) ulong = x ? x.height : 0ul

would've been the solution.
