c macro type casting
In C and C++, macros are quite literally in-place replacement. The preprocessor will encounter these #define s and replace them as it finds them. That's how you can nest macros inside of macros and it only takes 1 pass to preprocess.,I don't believe you can wrap types in arbitrary levels of parentheses.* So this compiles fine: ((*(intptr_t*)&((Block1)))=(intptr_t)(Block1)^(intptr_t)(Block2) ... ,C Macro that effectively does hierarchical type casting.
