Module `Eio_unix.Process`Source

Spawning child processes with extra control.

This extends the Eio.Process API with more control over file-descriptors.

Sourceclass virtual mgr : object ... end

Source

val spawn_unix : 
  sw:Eio.Std.Switch.t ->
  mgr ->
  ?cwd:Eio.Fs.dir Eio.Path.t ->
  fds:(int * Fd.t * Private.Fork_action.blocking) list ->
  ?env:string array ->
  ?executable:string ->
  string list ->
  Eio.Process.t

spawn_unix ~sw mgr ~fds args spawns a child process running the command args.

The arguments are as for Eio.Process.spawn, except that it takes a list of FD mappings for Fork_action.inherit_fds directly, rather than just flows for the standard streams.

Sourceval sigchld : Eio.Condition.t

If an Eio backend installs a SIGCHLD handler, the handler will broadcast on this condition.

This allows non-Eio libraries (such as Lwt) to share its signal handler.

Note: Not all backends install a handler (e.g. eio_linux uses process descriptors instead), so be sure to call install_sigchld_handler if you need to use this.

Sourceval install_sigchld_handler : unit -> unit

install_sigchld_handler () sets the signal handler for SIGCHLD to broadcast sigchld.
