.Sh DESCRIPTION
|
2003-04-22 03:25:14 +00:00
|
|
|
.Pp
|
|
|
|
|
The
|
|
|
|
|
.Nm device_get_ivar
|
|
|
|
|
function returns the bus-specific instance variables of a device.
|
|
|
|
|
.Pp
|
|
|
|
|
The
|
|
|
|
|
.Nm device_set_ivar
|
|
|
|
|
function sets the bus-specific instance variables of a device.
|
|
|
|
|
.Pp
|
|
|
|
|
Typically, only bus drivers will use these functions.
|
|
|
|
|
The kernel assumes that the bus driver will manage this memory, and no
|
|
|
|
|
automatic memory allocation or deallocation happens.
|
|
|
|
|
Client drivers should access ivars through the
|
|
|
|
|
.Xr BUS_READ_IVAR 9
|
|
|
|
|
interface instead.
