WoW Watching IsDebuggerPresent?

[DrakeFish]

While browsing the WoW Functions, I saw some function calling the WinAPI function IsDebuggerPresent. I was wondering if this means that WoW (or warden) watches for that? I know that this function is easily patchable anyways, but does anyone know if it's really used?

[bind]

Have you bothered even checking for references to the IsDebuggerPresent API or perhaps put a breakpoint on the instance?

A little work goes a long way

Afaik WoW does use that API, but to support their own debugging.
Maybe I mix up games, was reversing 7 games in last 2 months, lol.

Up p __invoke_watson+DC call ds:IsDebuggerPresent
Up p ___report_gsfailure+BB call ds:IsDebuggerPresent
Up r __invoke_watson+DC call ds:IsDebuggerPresent
Up r ___report_gsfailure+BB call ds:IsDebuggerPresent

You know, just xrefing it isn't that hard.
