| /** |
| * This header contains the builtin types available for arguments and return |
| * values, representing their C counterparts. They are used inside higher-order |
| * macros that the user must call, providing a macro that will consume the |
| * arguments provided to it by the higher-order macro. The macros exposed are: |
| * |
| * CTYPES_FOR_EACH_BOOL_TYPE(macro) |
| * CTYPES_FOR_EACH_CHAR_TYPE(macro) |
| * CTYPES_FOR_EACH_CHAR16_TYPE(macro) |
| * CTYPES_FOR_EACH_INT_TYPE(macro) |
| * CTYPES_FOR_EACH_WRAPPED_INT_TYPE(macro) |
| * CTYPES_FOR_EACH_FLOAT_TYPE(macro) |
| * CTYPES_FOR_EACH_TYPE(macro) |
| * |
| * The macro name provided to any of these macros will then be repeatedly |
| * invoked as |
| * |
| * macro(typename, ctype, ffitype) |
| * |
| * where 'typename' is the name of the type constructor (accessible as |
| * ctypes.typename), 'ctype' is the corresponding C type declaration (from |
| * which sizeof(ctype) and templated type conversions will be derived), and |
| * 'ffitype' is the ffi_type to use. (Special types, such as 'void' and the |
| * pointer, array, and struct types are handled separately.) |
