debugging - Is it possible to get a core dump of a running process and its symbol table?

Is it possible to get gdb or use some other tools to create a core dump of a running process and it's symbol table? It would be great if there's a way to do this without terminating the process.

If this is possible, what commands would you use? (I'm trying to do this on a Linux box)

Or run gcore $(pidof processname).

This has the benefit (over running gdb and issuing commands to the CLI) that you attach and detach in the shortest possible time.
