Description

This is the simplest example that shows how to use TLS (Thread Local Storage) callbacks to execute code before the system transfers controls to program's main entry point. There's nothing new here. Elicz did that in 2000 already, but as I played with TLS recently, so... here it is.
Hint: to debug applicatons that use TLS, you can use NtGlobalGlag plug-in for OllyDbg.

If you happen to use my code, it would be nice if you credit KaKeeware.
