Function name built from macro using given string and argument

Question

I am currently having a problem defining a macro in C ++.

I want like this:

#define MY_MACRO (Name, Address) __int32 Get_Name() { return Address; }

Now when I call it like this:

MY_MACRO(Test, 0x10);

he spits out

__int32 Get_Name() { return 0x10; }
            ^^^^

instead

__int32 Get_Test() { return 0x10; }
            ^^^^

How can I solve this problem? I really need Get_

in the name and then the name passed by the argument.

You have to concatenate strings this way

#define MY_MACRO(Name, Address) __int32 Get_##Name() { return Address; }

Use the macro concatenation operator .

#define MY_MACRO (Name, Address) __int32 Get_##Name() { return Address; }
