Pointer to interrupt

I have some code that works, but it annoys me that I get a compilation warning.

This is a DOS program written with MSVC 1.52, large memory model.

I declare a pointer to an interrupt as so:-

void (_cdecl _interrupt _far *_based(_segname("_CODE"))oldClockInt)(void) = NULL;

and then use it in the code as so:-

oldClockInt = _dos_getvect(8U);

The warning I get is:-
warning C4113: function parameter lists differed

It annoys the hell out of me to get warnings. Other than turning the warning off, how can I define this pointer correctly?

I cannot test it 'cos I have no MSVC, but in BC would work.

================================
void (_cdecl _interrupt _far
       *_based(_segname("_CODE"))oldClockInt)(void) = NULL;

oldClockInt = (void (_cdecl _interrupt far
       *_based(_segname("_CODE")) )(void)) _dos_getvect(8U);
================================

The unic problem is that _dos_getvect returns void*.
You may like to "typedef" that type of data, as to refer to it easyly.

Please, tell me if it works.

Thanks. That did it.
I could not see the solution myself since I was thinking it was the declaration rather than the call that was in error.
