I have been using this function to generate a "random" number:
static UInt16 rand( UInt16 max )
{
return ( SysRandom(TimGetTicks()) % max );
}
Unfortunately, this only works as expected on an emulated Palm IIIc and
fails on all other devices. On the devices on which it fails, the problem
is that successive calls in a tight loop generate the same number. For
example:
for ( i=0; i<25; i++ )
a[i] = rand(5) + 1;
On an emulated Palm Vx, this might produce the sequence
4,5,5,1,1,2,4,4,5,5,1,3,3,4,4,5,2,2,3,3,4,1,1,2,2
On some devices it is even worse, producing sequences like
4,4,4,4,1,1,3,3,5,5,5,5,2,2,2,2,2,2,3,3,4,4,4,4,2
On an emulated Palm IIIc, this produces a more reasonable
3,4,5,2,3,4,1,2,3,4,2,3,5,1,2,4,5,1,4,5,1,3,4,5,2
Does anyone know why this is happening? Does anyone have a better idea for
generating a more random series?
