thanks for your attention. When I try to call my new system call, it always returns -1. I then check the error message using perror( ). The error message is always "Bad Address". Could anybody please tell me what can cause a system call to return "Bad Address" error. All my variables are initialized and defined. Thanks in advance for any insights from you. saurabh desai <sdesai@ecs.fullerton.edu>
