GDB - The GNU Debugger. It use the "ptrace" function in Linux to do these things. It is also a source level debugger if you compiled the program with the "-g" switch. If you just want to see what system calls the program issued, then use the "strace" command. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its content is protected by law.
