ddi_getiminor(9F) Kernel Functions for Drivers ddi_getiminor(9F)NAMEddi_getiminor - get kernel internal minor number from an external dev_t
SYNOPSIS
#include <sys/types.h>
#include <sys/mkdev.h>
#include <sys/ddi.h>
minor_t ddi_getiminor(dev_t dev);
INTERFACE LEVEL
This interface is obsolete. getminor(9F) should be used instead.
PARAMETERS
The following parameters are supported:
dev Device number.
DESCRIPTIONddi_getiminor() extracts the minor number from a device number. This
call should be used only for device numbers that have been passed to
the kernel from the user space through opaque interfaces such as the
contents of ioctl(9E) and putmsg(2). The device numbers passed in using
standard device entry points must continue to be interpreted using the
getminor(9F) interface. This new interface is used to translate between
user visible device numbers and in kernel device numbers. The two num‐
bers may differ in a clustered system.
For certain bus types, you can call this DDI function from a high-
interrupt context. These types include ISA and SBus buses. See sys‐
bus(4), isa(4), and sbus(4) for details.
CONTEXTddi_getiminor() can be called from user context only.
RETURN VALUES
The minor number or EMINOR_UNKNOWN if the minor number of the device is
invalid.

WARNINGS
Drivers are required to replace calls to ddi_getminor.9f by getmi‐
nor(9F)) in order to compile under Solaris 10 and later versions.
