Hi Thanks for your help. I am sorry the symbols came in 'cos I included a test program that tests this module in the same makefile that did the module. I apologize for the inconvenience that I may have caused. Now I don't get these unresolved externals but I get a different error. I will try to fix it myself before I post another question in the newsgroup. Thanks for your time and your help. Vijay -- Kernelnewbies: Help each other learn about the Linux kernel.
