test availability of variables in context from user command


Hello,

I want to check the availability of a variable (var1 for instance) in the context from an user command but I don't find any way to do this.
Here is a (dummy) example of what I want to do :


void func1(void)
{
   int var2 = 2;
   ...
}

int main(int argc, char **argv)
{
 int var1 = 1;

 ...
 func1();
}

My gdb command:
define myfunc
 if defined(var1)
    $res = $var1
 else
    $res = $var2
 end
 ...
end

If I break into main, res should be equals to 1, else res should be equals to 2.

Is there a way to do this with gdb?

Thanks,
Christophe.
