NAME         top

       genl - generic netlink utility frontend

SYNOPSIS         top

       genl [ -s[tatistics] ] [ -d[etails] ] [ -r[aw] ] OBJECT

       genl { -V[ersion] | -h[elp] }

       OBJECT := { ctrl CTRL_OPTS }

       CTRL_OPTS := { help | list | monitor | get PARMS }

       PARMS := { name NAME | id ID }

DESCRIPTION         top

       The genl utility provides a simple frontend to the generic
       netlink library. Although it's designed to support multiple
       OBJECTs, for now only the ctrl object is available, which is used
       to query the generic netlink controller.

       The generic netlink controller can be queried in various ways:

       help   This command just prints a help text for the ctrl object.

       list   Show the registered netlink users.

              Listen for generic netlink notifications.

       get    Query the controller for a given user, identified either
              by name or id.
