If you're familiar with dup(2) *nix system call, you know that if you issue it from the process space to an open file, you can remap any file descriptor to a new file and all subsequent calls to read/write(2) will read/write from/to the file. Thus the simple idea behind dupx is to use gdb to attach to the process and then do a dup(2) call on its file descriptors.
