Data Structures for Drivers                           modldrv(9S)

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_link info;
     struct dev_ops    *drv_dev_ops;

     drv_modops
           Must  always  be  initialized  to   the   address   of
           mod_driverops.  This  identifies the module as a load-
           able driver.

     drv_linkinfo
           Can be any string up to MODMAXNAMELEN, and is used  to
           describe  the  module. This is usually the name of the
           driver, but can contain other information  such  as  a
           version number.

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