Question

I want to do a function to get a pointer on a struct.
I done this :

void *getTokenList() {
    static t_token *list;

    return &list;
}

At compilation, I have this warning :
warning: variable ‘list’ set but not used [-Wunused-but-set-variable]

Is it possible to disable this warning for this function (only this one), or put an GCC attribute on this variable to hide this warning?

I had put #pragma GCC diagnostic ignored "-Wunused-but-set-variable" in top of my file but I want to hide this warning ONLY for this variable in this function.

Thanks,
Jean

You can use this to shut it off:

(void)list;

Alternatively and less portably you can use __attribute__((unused)).
