How can I make sure that nobody has hooked the same functions/syscalls that I have- or want to hook? The first problem can of course be solved by making a checksum of the original function that I want to override, and comparing the result before hooking. OTOH this is not very portable, and does not solve the problem of someone overriding my hooks. Any help is much apreciated. -pwa. _____________________________________________ Free email with personality!
