Greetings!

Imagine,

//start
int getMe(int i)
{
  writefln(__LINE__);
  writefln(__FUNCTION_NAME__);
  return I + 1;
}

void main(args )
{
  getMe(1);
}
//end

So, the result would be,

4
getMe

So, is there a way to get the name of the function while in that function?  I know I can use some debugging and hard code it, but I would like to use it.

thanks.

So close! Use "__FUNCTION__" or "__PRETTY_FUNCTION__".
