=head1 NAME
nbd_get_version - return the version of the library
=head1 SYNOPSIS
#include <libnbd.h>
const char * nbd_get_version (
struct nbd_handle *h
);
=head1 DESCRIPTION
Return the version of libnbd. This is returned as a string
in the form C<"major.minor.release"> where each of major, minor
and release is a small positive integer. For example:
minor
↓
"1.0.3"
↑ ↑
major release
=over 4
=item major = 0
The major number was C<0> for the early experimental versions of
libnbd where we still had an unstable API.
=item major = 1
The major number is C<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 C<1>.
=item minor = 0, 2, ... (even)
The minor number is even for stable releases.
=item 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.
=item release
The release number is incremented for each release along a particular
branch.
=back
=head1 RETURN VALUE
This call returns a statically allocated string, valid for the
lifetime of the process or until libnbd is unloaded by
L<dlclose(3)>. You B<must not> try to free the string.
=head1 ERRORS
This function does not fail.
The following parameters must not be NULL: C<h>.
For more information see L<libnbd(3)/Non-NULL parameters>.
=head1 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
