| 7 * This header contains the builtin types available for arguments and return | |
| 8 * values, representing their C counterparts. They are listed inside macros | |
| 9 * that the #includer is expected to #define. Format is: | |
| 10 * | |
| 11 * DEFINE_X_TYPE(typename, ctype, ffitype) | |
| 12 * | |
| 13 * where 'typename' is the name of the type constructor (accessible as | |
| 14 * ctypes.typename), 'ctype' is the corresponding C type declaration (from | |
| 15 * which sizeof(ctype) and templated type conversions will be derived), and | |
| 16 * 'ffitype' is the ffi_type to use. (Special types, such as 'void' and the | |
| 17 * pointer, array, and struct types are handled separately.) | |
| 18 * | |
| 19 * This header lacks a #ifndef wrapper because it is deliberately #included | |
| 20 * multiple times in ctypes/CTypes.h. | |
