Hello members.
I wish to ask if its possible to switch included .c or .h file.

Only thing what comes in mind is #ifdef, but how i could dynamically change it.

My target is more language files with same string names, but different values.

You cannot switch dynamically included .c oh .h files. They are assembled at compiletime.

Uhrwerk is right, that is not possible since the compiler adds the include files BEFORE he compiles the script. It does not include them during runtime.
