related to the project described in my last post (removing duplicate
items in a vector file), do the standard grass functions write points
in some particular order, or should I have to sort the x/y vectors
in the line_pnts structure before I make a "one pass" comparison?
by "one pass" comparison, I mean:
for (i = 0; i < Points_a->n_points; ++i)
{
if (iszero (Points_a->x[i] - Points_b->x[i]) &&
iszero (Points_a->y[i] - Points_b->y[i]))
match++;
}
match = (match == Points_a->n_points) ? 1 : 0;
comparing Points_a with Points_b.
