NAME

6       nbd_get_version - return the version of the library

SYNOPSIS

9        #include <libnbd.h>
10
11        const char * nbd_get_version (struct nbd_handle *h);
12

DESCRIPTION

14       Return the version of libnbd.  This is returned as a string in the form
15       "major.minor.release" where each of major, minor and release is a small
16       positive integer.  For example:
17
18            minor
19              ↓
20           "1.0.3"
21            ↑   ↑
22        major   release
23
24       major = 0
25           The major number was 0 for the early experimental versions of
26           libnbd where we still had an unstable API.
27
28       major = 1
29           The major number is 1 for the versions of libnbd with a long-term
30           stable API and ABI.  It is not anticipated that major will be any
31           number other than 1.
32
33       minor = 0, 2, ... (even)
34           The minor number is even for stable releases.
35
36       minor = 1, 3, ... (odd)
37           The minor number is odd for development versions.  Note that new
38           APIs added in a development version remain experimental and subject
39           to change in that branch until they appear in a stable release.
40
41       release
42           The release number is incremented for each release along a
43           particular branch.
44

RETURN VALUE

46       This call returns a statically allocated string, valid for the lifetime
47       of the process or until libnbd is unloaded by dlclose(3).  You must not
48       try to free the string.
