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 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 ver-
           sion information, but can contain other information as
           well.

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