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

spec_type of the file,
either
S_IFCHR or
S_IFBLK. See
ddi_create_minor_node(9F) for a
description 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
