You need shared memory or some other form of interprocess communication.
Pure C cannot do what you want except by overly cumbersome ways or my
making system specific assumptions (example: that the system employs no
memory protection etc.). You will get better answers and ideas if you
ask in a group for you system like comp.unix.programmer for UNIX and
clones and comp.os.ms-windows.programmer.win32 for Windows machines.
