Sourceval log : Log.logger

Sourceval fork : unit -> [> `Child | `Forked of int ]

Sourceval unparent : unit -> unit

fork off and die

Sourceval daemonize : unit -> unit

Sourceval write_pidfile : string -> unit

Sourceval read_pidfile : string -> int

Source

val probe_pidfile : 
  string ->
  [> `Alive of int | `Error of exn | `Missing | `Stale ]

Sourceval check_pidfile : string -> unit

Sourceval manage_pidfile : string -> unit

Sourceval restart : ('a -> 'b) -> 'a -> 'b

Sourceval handle_sig_exit_with : exit:bool -> (unit -> unit) -> unit

NB be careful with mutexes in signal handlers. Outputting anything to ocaml channels is a potential deadlock. Use signalfd which invokes signal handlers in predictable context.

deprecated
easy to deadlock, use signalfd instead

Sourceval handle_sig_reload_with : (unit -> unit) -> unit

deprecated
easy to deadlock, use signalfd instead

Sourceval show_addr : Unix.sockaddr -> string

Sourceval get_inet_addr_exn : Unix.sockaddr -> Unix.inet_addr

Sourceval show_inet_addr_exn : Unix.sockaddr -> string

Sourceval make_inet_addr_exn : string -> int -> Unix.sockaddr

Sourceval inet_addr_of_string : string -> Unix.sockaddr

Sourceval unix_addr_of_string : string -> Unix.sockaddr

Sourceval parse_addr_port_exn : string -> string * int

Sourceval parse_ip_port_exn : string -> Unix.inet_addr * int

Parse input as ip:port

returns
a tuple representing ip and port

Sourceval sockaddr_of_string : string -> Unix.sockaddr

Convert a string to a Unix.sockaddr.

Formats supported are:

unix:file_path
host:port
*:port, using Unix.inet_addr_any
port, using Unix.inet_addr_loopback

Sourceval read_process : string -> string

Execute process and capture stdout to string,

returns
empty string on error

module Ev = Libevent

Sourceval output_process_exit : string -> Unix.process_status IO.output

returns
IO.t to feed stdin of spawned process

Sourceval output_process : string -> unit IO.output

returns
IO.t to feed stdin of spawned process

Sourceval write_process_exn : string -> Bytes.t -> unit

Sourceval write_process : string -> Bytes.t -> bool

Sourceval mounts : unit -> (string * string * string list) list

Sourceval find_mount : string -> string * string * string list

parameter path
must be normalized

Sourceval sleep : float -> unit

Sourceval output_buf_fd : ?bufsize:int -> Unix.file_descr -> unit IO.output

Buffered output to Unix.file_descr. Doesn't own the file descriptor.

Sourceval unlimit_soft : Devkit_core.Prelude.U.resource -> unit

Sourceval raise_limits : unit -> unit

raise core and nofile soft limits (to the corresponding hard limits)

Sourceval connect : Unix.file_descr -> Unix.sockaddr -> unit

Sourceval connect_lwt : Lwt_unix.file_descr -> Lwt_unix.sockaddr -> unit Lwt.t

Sourceval get_xdg_dir : env:string -> string -> string

Sourceval xdg_cache_dir : string lazy_t

Sourceval xdg_config_dir : string lazy_t

Sourceval quote_if_needed : string -> string

Sourceval args : string list

Sourceval cmdline : string
