c macro define function
Function like Macros. You can also define macros that work in a similar way like a function call. This is known as function-like macros. For example, , #define printf(a, b, ...) my_printf(x, a, b, ...) 下面這二種用法在GNU GCC 或者符合C99 標準的C 編譯器preprocessor 有支援. // ..., You can as follows #define foo(x) ((x) > 32 ? (x) : (2 * (x))). But that evaluates x multiple times. You can instead create a static function, which is ...,To define a function-like macro, you use the same ' #define ' directive, but you put a pair of parentheses immediately after the macro name.
