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
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 node_type
parameter.
