Module Unix

module Unix: sig .. end

Extensions to Core.Unix.

val fork_exec : ?stdin:Core.Unix.File_descr.t ->
       ?stdout:Core.Unix.File_descr.t ->
       ?stderr:Core.Unix.File_descr.t ->
       ?path_lookup:bool ->
       ?env:[ `Extend of (string * string) list | `Replace of (string * string) list ] ->
       ?working_dir:string ->
       ?setuid:int -> ?setgid:int -> string -> string list -> Core.Std.Pid.t

fork_exec prog args ~stdin ~stdout ~stderr ~setuid ~setgid forks a new process that executes the program in file prog, with arguments args. The pid of the new process is returned immediately; the new process executes concurrently with the current process.

The function raises EPERM if when using set{gid,uid} and the user id is not 0.

The standard input and outputs of the new process are connected to the descriptors stdin, stdout and stderr.

The close_on_exec flag is cleared from stderr stdout and stdin so it's safe to pass in fds with close_on_exec set.

path_lookup : if true than we use PATH to find the process to exec.
