Problem with calling Kernel32 function "Sleep()"

[KlausVKragelund]

Hi there

I cannot seem to get this to work. In LabWindows I want to be able to call the Sleep function.

But when I #Include "Windows.h" I get errors that it cannot build:
"Redeclearation of 'CVI_GetFileSize' previous declared at utility.h:249"

The error stems from Winbase.h, which is included in Windows.h. The relevant
lines in Winbase.h is:

WINBASEAPI
DWORD
WINAPI
GetFileSize(
HANDLE hFile,
LPDWORD lpFileSizeHigh
);


Anybody had this error. Utility.h is a header that is included for other
function vital to Labwindows and it seems odd to me that there is
declaration overlap.....

Thanks

Hello

Make sure you include windows.h as the very first header in your header section.

Hope this helps

Thanks Bilal

That worked like a charm 🙂

A tip for anyone else trying to implement sleep().  If the include windows.h generates compiler errors, you can also try basicsdk.h.
This will give you sleep() functionality without all the extra declarations that can cause problems with CVI.
