nbd_get_version3

Usage

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

Overview

Return the version of libnbd. This is returned as a string in the form "major.minor.release" where each of major, minor and release is a small positive integer. For example:

     minor
       ↓
    "1.0.3"
     ↑   ↑
 major   release

major = 0

The major number was 0 for the early experimental versions of libnbd where we still had an unstable API.

major = 1

The major number is 1 for the versions of libnbd with a long-term stable API and ABI. It is not anticipated that major will be any number other than 1.

minor = 0, 2, ... (even)

The minor number is even for stable releases.

minor = 1, 3, ... (odd)

The minor number is odd for development versions. Note that new APIs added in a development version remain experimental and subject to change in that branch until they appear in a stable release.

release

The release number is incremented for each release along a particular branch.

Return value

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

Errors

This function does not fail.

The following parameters must not be NULL: "h". For more information see "Non-NULL parameters" in libnbd(3).

Version

This function first appeared in libnbd 1.0.

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

 #define LIBNBD_HAVE_NBD_GET_VERSION 1
