NAME
     modinfo - display information about loaded kernel modules

SYNOPSIS
     /usr/sbin/modinfo [-c] [-w] [-i module-id]


DESCRIPTION
     The modinfo utility displays information  about  the  loaded
     modules. The format of the information is as follows:

       Id Loadaddr Size Info Rev Module Name



     where Id is the module ID, Loadaddr  is  the  starting  text
     address  in hexadecimal, Size is the size of text, data, and
     bss in hexadecimal bytes, Info is module  specific  informa-
     tion,  Rev  is  the revision of the loadable modules system,
     and Module Name is  the  filename  and  description  of  the
     module.


     The module specific information is the block  and  character
     major numbers for drivers, the system call number for system
     calls, and unspecified for other module types.

OPTIONS
     The following options are supported:

     -c              Display  the  number  of  instances  of  the
                     module   loaded  and  the  module's  current
                     state.


     -i module-id    Display information about this module only.


     -w              Do not truncate  module  information  at  80
                     characters.


EXAMPLES
     Example 1 Displaying the Status of a Module


     The following example displays the status of module 2:


       example% modinfo -i 2

     Example 2 Displaying the Status of Kernel Modules


     The following example displays the  status  of  some  kernel
     modules:


       example% modinfo
       Id Loadaddr   Size Info Rev Module Name
        2  ff08e000   1734   -   1  swapgeneric
        4  ff07a000   3bc0   -   1  specfs (filesystem for specfs)
        6  ff07dbc0   2918   -   1  TS (time sharing sched class)
        7  ff0804d8    49c   -   1  TS_DPTBL (Time sharing dispatch table)
        8  ff04a000  24a30   2   1  ufs (filesystem for ufs)

       Id    Loadcnt Module Name                            State
         1          0 krtld                            UNLOADED/UNINSTALLED
