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 information, 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 unspeci-

       -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
       Id   Loadaddr   Size Info Rev Module Name
	2    ff08e000	1734   -   1  swapgeneric (root and swap configuration)

       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)
	9  ff080978   c640 226	 1  rpcmod (RPC syscall)
	9  ff080978   c640   -	 1  rpcmod (rpc interface str mod)
       10  ff08cfb8  2031c   -	 1  ip (IP Streams module)
       10  ff08cfb8  2031c   2	 1  ip (IP Streams device)

       Using the modinfo command with the -c option displays the number of instances of the module loaded and the module's current state.

       example% modinfo -c
       Id    Loadcnt Module Name			    State
	 1	    0 krtld			       UNLOADED/UNINSTALLED
	 2	    0 genunix			       UNLOADED/UNINSTALLED
	 3	    0 platmod			       UNLOADED/UNINSTALLED
	 4	    0 SUNW,UltraSPARC-IIi	       UNLOADED/UNINSTALLED
	 5	    0 cl_bootstrap		       UNLOADED/UNINSTALLED
	 6	    1 specfs			       LOADED/INSTALLED
	 7	    1 swapgeneric		       UNLOADED/UNINSTALLED
	 8	    1 TS			       LOADED/INSTALLED
	 9	    1 TS_DPTBL			       LOADED/INSTALLED
	10	    1 ufs			       LOADED/INSTALLED
	11	    1 fssnap_if 		       LOADED/INSTALLED
