Given a variadic macro of the form: #define MY_CALL_RETURN_F(FType, FId, ...) \\ if(/*prelude omitted*/) {\\
Our C/C++ project is using a new internal script that liberally wraps every function in SWIG to make available to python scripts.It chokes on our logger function since SWIG cannot wrap variadic functi
Is there any way to write a macr开发者_运维百科o like this: #define G(x1, x2, ... , xn) f(x1), f(x2), ... , f(xn)
I\'m currently looking to calculate the total size of arguments passed into a function, in bytes.In theory, one can just write out sizeof(x) for every argument.However, this is a tremendous waste of t
I\'m working with a library that includes a set of preprocessor libraries.One of them is a FOR_EACH style macro which iterates over a __VA_ARGS__ and calls a user-provided macro for each argument.The
So, according to this answer, C++ doesn\'t support variadic macros, and the C++ standard doesn\'t mention variadic macros anywhere.I know that C99 introduced variadic macros with __VA_ARGS__, and cert
There is a well-known problem with empty args for variadic macros in C99. example: #define FOO(...)printf(__VA_ARGS__)
What\'s the trick to create a variadic macro FOO(a1, a2, a3,..., an) such that it expands to FOOn(a1, a2, a3,..., an) for values of n in whatever preselected bo开发者_运维问答unded range you choose? T
I\'m trying to generate a function declaration using a macro /* goal: generate int f(int a, float b) */
Consider this code: #define F(x, ...) X = x and VA_ARGS = __VA_开发者_运维技巧ARGS__ #define G(...) F(__VA_ARGS__)
