// The following code needs some explanation:
// This creates slices on top of the C memory buffers allocated before in
// order to safely and comfortably use them as arrays. First the void pointer
// is cast to a pointer to an array of the type that will be stored in the
// array. Because the size of an array is a constant, but the real array size
// is dynamic, we just use the biggest possible index value MaxIdx, to make
// sure it's always big enough. (Nothing is allocated by casting, so the size
// can be arbitrarily big.) So, if the array should store items of myType, the
// cast would be (*[MaxIdx]myItem)(myCMemPtr).
// From that array pointer a slice is created with the [start:end:capacity]
// syntax. The capacity must be set explicitly here, because by default it
// would be set to the size of the original array, which is MaxIdx, which
// doesn't reflect reality in this case. This results in definitions like:
