ddi_getiminor(9F)					   Kernel Functions for Drivers 					 ddi_getiminor(9F)

NAME

       ddi_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       This interface is obsolete.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.

DESCRIPTION

       ddi_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 trans-
       late between user visible device numbers and in kernel device numbers. The two numbers 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.

CONTEXT

       ddi_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 getminor(9F)) in order to compile under Solaris 10 and later versions.

NAME

       di_minor_devt, di_minor_name, di_minor_nodetype, di_minor_spectype - return libdevinfo minor node information

SYNOPSIS

       cc [ flag... ] file... -ldevinfo [ library... ]
       #include <libdevinfo.h>

       dev_t di_minor_devt(di_minor_t minor);

       char *di_minor_name(di_minor_t minor);

       char *di_minor_nodetype(di_minor_t minor);

       int di_minor_spectype(di_minor_t minor);

PARAMETERS

       minor	A handle to minor data node.

DESCRIPTION

	These functions return libdevinfo minor node information.

RETURN VALUES

       The di_minor_name() function returns the minor name. See ddi_create_minor_node(9F) for a description of the name parameter.

       The  di_minor_devt() function returns the dev_t value of the minor node that is specified by SYS V ABI. See getmajor(9F), getminor(9F), and
       ddi_create_minor_node(9F) for more information.

       The di_minor_spectype() function returns the spec_type of the file, either S_IFCHR or S_IFBLK. See ddi_create_minor_node(9F) for a descrip-
       tion of the spec_type parameter.

       The  di_minor_nodetype()function  returns  the  minor  node_type  of the minor node. See ddi_create_minor_node(9F) for a description of the
       node_type parameter.

ERRORS

       No errors are defined.
