If you're in C++ you could do this (or something like it):
auto p0 = &e->pointer_coordinates[0]; for (int i = 0; i < e->pointer_count; ++i) { auto &p = p0[i]; // use p }
If you're in C++ you could do this (or something like it):
auto p0 = &e->pointer_ coordinates[ 0];
for (int i = 0; i < e->pointer_count; ++i)
{
auto &p = p0[i];
// use p
}
