   *

   * - a pointer Main is created by just passing the data pointer
   * - a pointer to a datablock can be created with the type and id data pointer
   * - a pointer to data contained in a datablock can be created with the id type
   *   and id data pointer, and the data type and pointer to the struct itself.
   *
   * There is also a way to get a pointer with the information about all structs.
