# nbd\_get\_version(3)

return the version of the library

## NAME

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

## SYNOPSIS

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

## 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

  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)](/dlclose/3.md).  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)](/libnbd/3.md).

## 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
```
