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).  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
