MODLDRV(9S) Data Structures for Drivers MODLDRV(9S)

NAME

modldrv - linkage structure for loadable drivers

SYNOPSIS

#include <sys/modctl.h>

INTERFACE LEVEL

illumos DDI specific (illumos 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.
