NAME
       modldrv - linkage structure for loadable drivers

SYNOPSIS
       #include <sys/modctl.h>

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI)

DESCRIPTION
       The  modldrv  structure is used by device drivers to export driver spe‐
       cific information to the kernel.

STRUCTURE MEMBERS
       struct mod_ops	 *drv_modops;
       char		 *drv_linkinfo;
       struct dev_ops	 *drv_dev_ops;

       drv_modops      Must  always  be	 initialized   to   the	  address   of
		       mod_driverops.  This  member identifies the module as a
		       loadable driver.

       drv_linkinfo    Can  be	any  string  up	 to  MODMAXNAMELEN  characters
		       (including the terminating NULL character), and is used
		       to describe the module and its version number. This  is
		       usually	the  name  of  the  driver  and module version
		       information, but can contain other information as well.

       drv_dev_ops     Pointer to the driver's dev_ops(9S) structure.
