6 nbd_get_version - return the version of the library

10
11 const char * nbd_get_version (struct nbd_handle *h);
12
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
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.

51 This function does not fail.
52
53 The following parameters must not be NULL: "h". For more information
54 see "Non-NULL parameters" in libnbd(3).
55
57 This function first appeared in libnbd 1.0.
58
59 If you need to test if this function is available at compile time check
60 if the following macro is defined:
61
62 #define LIBNBD_HAVE_NBD_GET_VERSION 1
63
65 nbd_create(3), nbd_get_package_name(3), libnbd(3).
