Module Resolver_lwt_unix

Resolve URIs to endpoints using Unix system calls

Prebuilt resolvers

val system : Resolver_lwt.t

Use the Unix system name resolver via getaddrinfo and getservbyname

val static : (string, Conduit.endp) Stdlib.Hashtbl.t -> Resolver_lwt.t

static hosts constructs a resolver that looks up any resolution requests from the static hosts hashtable instead of using the system resolver.

Rewrite and service functions

val system_service : string -> Resolver_lwt.svc option Lwt.t

Perform service lookup using getservbyname

val static_service : string -> Resolver_lwt.svc option Lwt.t

Perform service lookup using the builtin Uri_services module

val system_resolver : Resolver_lwt.rewrite_fn

Rewrite function that uses the system_service and static_service to resolve hosts

Debugging Hooks

val debug : bool Stdlib.ref

If debug is true, the builtin resolvers will output their resolution responses via the debug_print function. The default value of debug is true if the CONDUIT_DEBUG environment variable is set, and false otherwise.

val debug_print : ((string -> string -> string -> string -> unit, Stdlib.out_channel, unit) Stdlib.format -> string -> string -> string -> string -> unit) Stdlib.ref

debug_print is called by the debug functions to output the results of resolution. Defaults to Printf.eprintf to go to the standard error.
