A MACRO question

[ManicQin]

Hi all.

Is there a way to iterate through a pre-defined list in pre-compile
time?
(not with for)

something like:

#define LIST int,double,float,string......
#define MAX 10
#define functionPattern(type) \
void return##type() { \
cout << #type << endl; \
}

//Replacing the next macro
#define functionCreator \
functionPattern(LIST[1]) \
functionPattern(LIST[2]) \
..
..
..
functionPattern(LIST[MAX])

Thanks

#define MAX 10
#define functionPattern(type) \

}

//Replacing the next macro
#define functionCreator  \
functionPattern(LIST[1]) \
functionPattern(LIST[2]) \
.
.
.
functionPattern(LIST[MAX])

Thanks

Please explain what this means:

void return##type() { \
cout << #type << endl; \
}

Is it even legal C++ code?

Yes, the Boost library provides some sophisticated (really unbelievable) macro
magic.

Thanks I looked at how Boost do it and because I cant use Boost
I could only steal their code... but it's too much work more work
than I can afford to spent on just saving few lines...


Thanks!
