NAME
      modunload - unload a module
 


SYNOPSIS
      modunload -i module_id  [ -e exec_file ]
 


DESCRIPTION
      modunload unloads a loadable module from the running system.
      The   module_id  is  the  ID  of  the  module  as  shown  by
      modinfo(1M). If ID is 0, all modules  that  were  autoloaded
      which  are  unloadable,  are  unloaded.   Modules  loaded by
      modload(1M) are not affected.
 


OPTIONS
      -i module_id
            Specify the module to be unloaded.
 
      -e exec_file
            Specify the name of  a  shell  script  or   executable
            image  file  to  be  executed  before  the  module  is
            unloaded.
             The first  argument  passed  is  the  module  id  (in
            decimal).  There are two additional arguments that are
            module specific. For loadable drivers, the second  and
            third  arguments  are  the  block  major and character
            major numbers respectively. For loadable system calls,
            the  second  argument  is  the system call number. For
            loadable exec classes,  the  second  argument  is  the
            index into the  execsw table.
              For loadable filesystems, the second argument is the
            index  into  the   vfssw  table.  For loadable streams
            modules, the second argument is  the  index  into  the
            fmodsw  table.   For  loadable scheduling classes, the
            second argument is the index into   the  class  array.
            Minus  one  is  passed  for  an argument that does not
            apply.
