nbd\_get\_version(3) LIBNBD nbd\_get\_version(3)

# [NAME](#NAME)

nbd\_get\_version - return the version of the library

# [SYNOPSIS](#SYNOPSIS)

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

# [DESCRIPTION](#DESCRIPTION)

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](#major)

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

[major = 1](#major~2)

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)](#minor)

The minor number is even for stable releases.

[minor = 1, 3, ... (odd)](#minor~2)

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](#release)

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

# [RETURN VALUE](#RETURN_VALUE)

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

# [ERRORS](#ERRORS)

This function does not fail.

The following parameters must not be NULL: "h". For more information see "Non-NULL parameters" in [**libnbd**(3)](/man/os/libnbd/libnbd.3).

# [VERSION](#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
```
