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 specific 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.
