Question about handshake_receiver in IPC

I find before handle IPC, we always call handshake_receiver function.
A basic question is why do we need to handshake receiver? What do we
do when we handshake_receiver?

Another thing I note is we have separate handshake_receiver
if the receiver is on the other core.
What is the difference between those two handshake_receiver functions?

Thank you very much.
