c++ simple hashing function help

[mkosloff]

does anyone have the c++ code for a simple hashing function with a modulo? i am trying to figure out how to read numbers from a data file and hash them into specific locations using a simple modulo function, any help would be greatly appreciated.

This one is from a sample by... Marc Weiss, I think.

int hash( int key, int tableSize )
        {
            if( key < 0 ) key = -key;
            return key % tableSize;
        }
