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.
