Storing entire process state on disk and restoring it later? (On Linux/Unix)

Question

I would like to know: Is there a system call, library, kernel module or command line tool I can use to store the complete state of a running program on the disk?

Answer 1

A core dump is basically this, so yes, it must be possible to get.

What you really want is a way to restore that dump as a running program. That might be more difficult.
