How to get userID when writing Linux kernel module

Question

Here is my function in my kernel module which I insert using insmod command after make at later stages. I am working on goldfish (2.6.29)

You could perhaps use this:

 #include 

 static int getuid()
 {
     return current_uid();
 }

cred stands for "credentials", and this macro returns the user-id of the currently active credentials. Bear in mind however that the "current user id" can mean multiple things in Linux.
