NAME

       libnbd-ocaml - how to use libnbd from OCaml

SYNOPSIS

        let nbd = NBD.create () in
        NBD.connect_uri nbd "nbd://localhost";
        let size = NBD.get_size nbd in
        printf "%Ld\n" size

DESCRIPTION

       This manual page documents how to use libnbd to access Network Block Device (NBD) servers
       from the OCaml programming language.  The OCaml bindings work very similarly to the C
       bindings so you should start by reading libnbd(3)..

HANDLES

       Create a libnbd handle of type "NBD.t" by calling "NBD.create ()".

       You can either close the handle explicitly by calling "NBD.close" or it will be closed
       automatically when it is garbage collected.  If you call any other method on a handle
       which you have explicitly closed then the API will throw an "NBD.Closed" exception.

ERRORS

       Libnbd errors are turned automatically into "NBD.Error (str, errno)" exceptions.  This
       exception has two parameters.  The first is a string which is the printable error message.
       The second is the raw "errno", if available (see nbd_get_errno(3)).  The raw "errno" is
       not compatible with errors in the OCaml "Unix" module unfortunately.

EXAMPLES

       This directory contains examples written in OCaml:
