NAME

6       nbd_get_version - return the version of the library
7

SYNOPSIS

9        #include <libnbd.h>
10
11        const char * nbd_get_version (
12                       struct nbd_handle *h
13                     );

DESCRIPTION

16       Return the version of libnbd.  This is returned as a string in the form
17       "major.minor.release" where each of major, minor and release is a small
18       positive integer.  For example:
19
20            minor
21              ↓
22           "1.0.3"
23            ↑   ↑
24        major   release
25
26       major = 0
27           The major number was 0 for the early experimental versions of
28           libnbd where we still had an unstable API.
29
30       major = 1
31           The major number is 1 for the versions of libnbd with a long-term
32           stable API and ABI.  It is not anticipated that major will be any
33           number other than 1.
34
35       minor = 0, 2, ... (even)
36           The minor number is even for stable releases.
37
38       minor = 1, 3, ... (odd)
39           The minor number is odd for development versions.  Note that new
40           APIs added in a development version remain experimental and subject
41           to change in that branch until they appear in a stable release.
42
43       release
44           The release number is incremented for each release along a
45           particular branch.
46

RETURN VALUE

48       This call returns a statically allocated string, valid for the lifetime
49       of the process or until libnbd is unloaded by dlclose(3).  You must not
50       try to free the string.
51

ERRORS

60
61       If you need to test if this function is available at compile time check
62       if the following macro is defined:

64        #define LIBNBD_HAVE_NBD_GET_VERSION 1
