Simple Win32 timer DLL

Have lots of spare time today, so here goes nothing ;D

Attached is a simple timer DLL for Win32 meant to be accessed from C or probably C++. Actually I stole the code from BASELIB's "bkernel.asm" source. These two routines use QueryPerformanceCounter. You can use them without any time.h hassle in your source. Example

Code:

//
// Demo using timer functions from timer32.dll
// gcc -m32 this.c timer32.dll -o this.exe
//
#include <stdio.h>

extern int* timer_on();         //from timer32.dll
extern void timer_off(int *);   //from timer32.dll      

int main()
{
        double x = 45.3345;
        int *p = NULL;

        p = timer_on();
        
        //timed loop
        for (int y=1000; y > 0; y--) 
            printf("%.4f",x);

        timer_off(p);

        return (0);
}

Should print the output of the timed code and the output of timer in seconds. I would probably make the linux and 64-bit versions if time permits.

Source code, the DLL and C test code are attached. Happy working, peeps! ;D
