module Fork_action : sig ... end
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.
