The special bint type is used for C boolean values (int with 0/non-0 values for False/True) and Py_ssize_t for (signed) sizes of Python containers. Pointer types are constructed as in C when using Cython syntax, by appending a * to the base type they point to, e.g. int** for a pointer to a pointer to a C int.
