DESCRIPTION

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

STRUCTURE MEMBERS

20         struct mod_ops    *drv_modops;
21         char              *drv_linkinfo;
22         struct dev_ops    *drv_dev_ops;
23
24
25       drv_modops       Must  always  be  initialized  to   the   address   of
26                        mod_driverops.  This member identifies the module as a
27                        loadable driver.
28
29
30       drv_linkinfo     Can be  any  string  up  to  MODMAXNAMELEN  characters
31                        (including  the  terminating  NULL  character), and is
32                        used to describe the module and  its  version  number.
33                        This is usually the name of the driver and module ver‐
34                        sion information, but can contain other information as
35                        well.

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