NAME

     modstat -- display status of loaded kernel modules


SYNOPSIS

     modstat [-Aaen] [name]


DESCRIPTION

     The modstat utility displays the status of any kernel modules present in
     the kernel.

     The options are as follows:

     -A      Tells you whether or not modules can be autoloaded at the moment.
             This option does take into consideration the sysctl
             kern.module.autoload.

     -a      Tells you whether or not modules can be autoloaded at the moment.
             This option does not take into consideration the sysctl
             kern.module.autoload.

     -e      Tells you whether or not you may load a module at the moment.

     -n name
             Display the status of only the module with this name.  Please
             note that -n is optional.

     In addition to listing the currently loaded modules' name, the informa-
     tion reported by modstat includes:

     CLASS     Module class, such as "vfs", "driver", "exec", "misc" or "sec-
               model".

     SOURCE    Where the module was loaded from.  "builtin" indicates that the
               module was built into the running kernel.  "boot" indicates
               that the module was loaded during system bootstrap.  "filesys"
               indicates that the module was loaded from the file system.

     SIZE      Size of the module in bytes.

     REFS      Number of references held on the module.  Disabled builtin mod-
               ules will show a count of -1 here.

     ADDRESS   The kernel address at which the module is loaded.  Builtin mod-
               ules will show 0 here.

     REQUIRES  Additional modules that must be present.


EXIT STATUS

     The modstat utility exits with a status of 0 on success and with a
     nonzero status if an error occurs.
