Thread: Macros as functions

Why isn't this working?

Macros:

Code:

#define KEYDOWN ( vKey ) ( ( GetAsyncKeyState ( vKey ) & 0x8000 ) ? TRUE  : FALSE )
#define KEYUP   ( vKey ) ( ( GetAsyncKeyState ( vKey ) & 0x8000 ) ? FALSE : TRUE  )

Global variables:

Code:

int vKey;

Code:

Code:

if ( KEYDOWN ( VK_ESCAPE ) )
	SendMessage ( hWnd, WM_CLOSE, 0, 0 );

Error:

Code:

Error	1	error C2064: term does not evaluate to a function taking 1 arguments 161

It works fine without the use of macros. What am I doing wrong?

Thanks.
