Since ages I use the following formula for creating a set of random integers for hashing at program start: #define LENGTH 64*12 int random [LENGTH]; int a,b,c,d,x; srand(9); // initialize prime number for (x=0; x<LENGTGH; x++) { a=rand(); b=rand(); if (b & 1) a=a | 0x8000; c=rand(); d=rand(); if (d & 1) c=c | 0x8000; random[x]=(a<<16)+c; } I wonder how good such a system is and how others do it. - Ed -
