.SH INTERFACE LEVEL

.SH DESCRIPTION
.sp
.LP
\fBddi_getiminor()\fR 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
\fBioctl\fR(9E) and \fBputmsg\fR(2). The device numbers passed in using
standard device entry points must continue to be interpreted using the
\fBgetminor\fR(9F) interface. This new interface is used to translate between
user visible device numbers and in kernel device numbers. The two numbers may
differ in a clustered system.
.sp
.LP
For certain bus types, you can call this \fBDDI\fR function from a
high-interrupt context.  These types include \fBISA\fR and SBus buses.  See
\fBsysbus\fR(4), \fBisa\fR(4), and \fBsbus\fR(4) for details.
.SH CONTEXT
.sp
.LP
\fBddi_getiminor()\fR can be called from user context only.
.SH RETURN VALUES
.sp
.LP
The minor number or \fBEMINOR_UNKNOWN\fR if the minor number of the device is
invalid.

Drivers are required to replace calls to \fBddi_getminor.9f\fR by
\fBgetminor\fR(9F)) in order to compile under Solaris 10 and later versions.
