Data Structures for Drivers                           modldrv(9S)



NAME
     modldrv - linkage structure for loadable drivers

SYNOPSIS
     #include 


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 char-
                      acters   (including  the  terminating  NULL
                      character), and is  used  to  describe  the
                      module and its version number. This is usu-
                      ally 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)  struc-
                      ture.
