IPC is InterProcess Communication, used for processes to talk to each other.
Doing inter-process communication without inter-process communication is a logical contradiction, and so is impossible.
To expand on this, you could do something simple like read and write from a file. That is (in some way) not a formal IPC mechanism, even though it does indeed accomplish communication between processes.
