type t

A child process.

module Fork_action = Eio_unix.Private.Fork_action

Setup actions to perform in the child process.

val spawn : sw:Eio.Std.Switch.t -> Fork_action.t list -> t

spawn ~sw actions forks a child process, which executes actions. The last action should be Fork_action.execve.

You will typically want to do Promise.await (exit_status child) after this.

val signal : t -> int -> unit

signal t x sends signal x to t.

This is similar to doing Unix.kill t.pid x, except that it ensures no signal is sent after t has been reaped.

val pid : t -> int

val exit_status : t -> Unix.process_status Eio.Std.Promise.t

exit_status t is a promise for the process's exit status.
