#define 宏用於 C 中的調試打印？ - #define macro for debug printing in C?

問題：

Trying to create a macro which can be used for print debug messages when DEBUG is defined, like the following pseudo code:嘗試創建可用於在定義 DEBUG 時打印調試消息的宏，如下面的僞代碼：

#define DEBUG 1
#define debug_print(args ...) if (DEBUG) fprintf(stderr, args)

How is this accomplished with a macro?這是如何通過宏實現的？
