NAME

6       libnbd-ocaml - how to use libnbd from OCaml
7

SYNOPSIS

9        let nbd = NBD.create () in
10        NBD.connect_uri nbd "nbd://localhost";
11        let size = NBD.get_size nbd in
12        printf "%Ld\n" size
13

DESCRIPTION

15       This manual page documents how to use libnbd to access Network Block
16       Device (NBD) servers from the OCaml programming language.
17
18       The OCaml bindings work very similarly to the C bindings so you should
19       start by reading libnbd(3).
20
21       For OCaml API documentation see NBD(3).
22

HANDLES

24       Create a libnbd handle of type "NBD.t" by calling "NBD.create ()".
25
26       You can either close the handle explicitly by calling "NBD.close" or it
27       will be closed automatically when it is garbage collected.  If you call
28       any other method on a handle which you have explicitly closed then the
29       API will throw an "NBD.Closed" exception.
30

ERRORS

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