problem with qsort

Luc Vercruysse

Hi,

When I use the C++ function qsort, it hangs when the data contains duplicated values.
Here is an example

unsigned char Array[] = {0,5,7,1,3,9,5};

int BCompare(const void* a, const void* b)
{
    return(*(u8*)a - *(u8*)b);
}


void main(void) {
        int i;
        printf("\n\rBefore Sort");
        for (i=0;i<7;i++) printf("%d,",Array[i]);
        qsort(Array, 7, sizeof(u8), BCompare);
        printf("\n\rAfter Sort");
        for (i=0;i<7;i++) printf("%d,",Array[i]);
}

With Array containing unique numbers, the sortfunction is OK
Any idea ?

Kind regards
Luc Vercruysse
