       Return the optional NBD export name if one was negotiated with the current client (this uses thread-local
       magic so no parameter is required).

       The export name is a free-form text string, it is not necessarily a path or filename and it does not need
       to begin with a '/' character.  The NBD protocol describes the empty string ("") as a representing a
       "default export" or to be used in cases where the export name does not make sense.

       "nbdkit_export_name" was added in nbdkit 1.16.

       In nbdkit-ocaml-plugin(3):

        NBDKit.export_name : unit -> string

       In nbdkit-python-plugin(3):

        import nbdkit
        name = nbdkit.export_name()

       In nbdkit-rust-plugin(3):

        use nbdkit::*;
        pub fn export_name() -> std::result::Result<String, Box<dyn error::Error>>

       In nbdkit-sh-plugin(3) the export name is available as parameter $3 of the "open" method.

       nbdkit_export_name - get the NBD export name for nbdkit

       The function returns a string.  The returned string is valid at least through the ".close" of the current
       connection, but if you need to store it in the plugin for use by more than one client you must copy it.

       If there is an error it calls nbdkit_error(3) and returns "NULL".
