在#define 宏中转义# 符号?
在不涉及血淋淋的细节的情况下，我想使用一个 #define 宏，该宏将扩展为一个 #include 但#"符号会混淆预处理器(如它认为我想引用一个论点.)
Without going into the gory details I want to use a #define macro that will expand to a #include but the '#' sign is confusing the preprocessor (as it thinks I want to quote an argument.)
例如，我想做这样的事情:
For example, I want to do something like this:
#define MACRO(name) #include "name##foo"
然后这样使用它:
MACRO(Test)
这将扩展为:
#include "Testfoo"
不起眼的 # 符号导致预处理器出错.MinGW 给我以下错误:
The humble # sign is causing the preprocessor to barf. MinGW gives me the following error:
'#'后面没有宏参数
我想我需要转义 # 符号，但如果这可能的话我不会.
I guess I need to escape the # sign but I don't if this is even possible.
是的，宏确实是邪恶的……
Yes, macros are indeed evil...
推荐答案
据我所知，你不能在定义中使用另一个预处理器指令.
As far as I remember you cannot use another preprocessor directive in define.
