When I run the own written function it runs and does no exit. I was waiting for 5-6 hours, checked dstats, no disk writes, only 1 core works and no memory usage. It is like stuck and can not exit. It happens when I use function separately for each variable, without callingm for example:

while( *a ){

        countA += *a & 1;

        *a >>= 1;

    }

   while( *b ){

        countB += *b & 1;

        *b >>= 1;

    }

   while( c ){

        countC += c & 1;

        c >>= 1;

    }

but when I call functions like this monetdb works fine:

int countSetBits1(unsigned int n){

        ! unsigned int count = 0;

        while(n){

            count += n & 1;

            n >>= 1;

        }

    return count;

    }    

countA = countSetBits1(*a);

countB = countSetBits1(*b);

countC = countSetBits1(c);

I am not strong in C or monetdb internals, but in Netbeans both codes work well. The entire code :

str

UDFbitanddec(flt *ret, lng *a, lng *b) {

    int c = 0;

    int countA = 0;

int countB = 0;

    int countC = 0;

int maxCount = 0;

unsigned int iA = *a;

unsigned int iB = *b;

    

    c = iA & iB;

    while( iA ){

        countA += iA & 1;

        iA >>= 1;

    }

   while( iB ){

        countB += iB & 1;

        iB >>= 1;

    }

   while( c ){

        countC += c & 1;

        c >>= 1;

    }

if (countA >= countB) {

maxCount = countA;

}

else {

maxCount = countB;

}

   

    *ret = (float)countC /maxCount;

    return MAL_SUCCEED;

    

}
