What is " IPC send completion sync"

Hi,

Can anyone explain to me what is meant by " IPC send completion sync". I searched on this subject here on the website and found that somewhere in 2003 someone already asked this question but he didn't get an answer.

Also on the internet it is hard to find the right answer.

I hope there is someone who found the answer in the past and can share it with me.

Greetings
