These didn't exist in early iPhone GL implementations, but according to this page: http://developer.apple.com/iphone/library/releasenotes/General/iPhone30APIDiffs/index.html they should be there in 3.0+, which I'm building for. But I'm getting "implicit definition" warnings. What do I need to do to get those functions? Thanks!

• How to convert between Enums where values share the same names ?

  - by Ross Watson

  Hi, if I want to convert between two Enum types, the values of which, I hope, have the same names, is there a neat way, or do I have to do it like this...? enum colours_a { red, blue, green } enum colours_b { yellow, red, blue, green } static void Main(string[] args) { colours_a a = colours_a.red; colours_b b; //b = a; b = (colours_b)Enum.Parse(typeof(colours_b), a.ToString()); } Thanks, Ross

  - by Álvaro

  Hi, I'm trying to make a little console application that is able to deal with keystrokes as events. What I need is mostly the ability to get the keystrokes and be able to do something with them without dealing with the typical stdin reading functions. I tried to check the code of programs like mplayer, which implement this (for stopping the play, for example), but I can't get to the core of this with such a big code base. Thanks
