Linux - how to create a process without running it?

Question

linux

Hello. I wonder if there is a possibility in Linux to create a process without starting it (run it after doing something with it)? This is, for example, like with threads - you can create and run later. I did not find an answer to this question on the Internet, everywhere there is only a way with fork, and the subsequent suspension of the process.

Answer 1

The fact is that the process itself is controlled by the OS scheduler and cannot be managed as a thread.
But you can write in the new process a transition to the waiting state and wait for a signal from the main program, after which perform some actions.
