nbd_get_version_extra(3)

NAME
nbd_get_version_extra - return the extra version of the library

SYNOPSIS
 #include <libnbd.h>

 const char * nbd_get_version_extra (
                struct nbd_handle *h
              );

DESCRIPTION
Return the extra version of libnbd. This is a freeform string which is set at package build time using:

 ./configure --with-extra="..."

and it intended to be used by downstream packagers (eg. Linux distributions) to convey extra version information, such as the precise version of the libnbd RPM, ".deb" etc.

The string may be "", indicating that no extra version information is available, or that this is an upstream build of libnbd.

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 1.24.

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_EXTRA 1
