Device Information Library Functions
                                                di_prop_lookup_bytes(3DEVINFO)



NAME
       di_prop_lookup_bytes,     di_prop_lookup_ints,    di_prop_lookup_int64,
       di_prop_lookup_strings, di_prop_exists - search for a property

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

       int di_prop_lookup_bytes(dev_t dev, di_node_t node,
            const char *prop_name, uchar_t **prop_data);


       int di_prop_lookup_ints(dev_t dev, di_node_t node,
            const char *prop_name, int **prop_data);


       int di_prop_lookup_int64(dev_t dev, di_node_t node,
            const char *prop_name, int64_t **prop_data);


       int di_prop_lookup_strings(dev_t dev, di_node_t node,
            const char *prop_name, char **prop_data);


       int di_prop_exists(dev_t dev, di_node_t node,
            const char *prop_name);

PARAMETERS
       dev          dev_t of minor node with which the property is associated.
                    DDI_DEV_T_ANY  is  a  wild  card that matches all dev_t's,
                    including DDI_DEV_T_NONE.


       node         Handle to the device node with which the property is asso‐
                    ciated.


       prop_data    For di_prop_lookup_bytes(), the address to a pointer to an
                    array of unsigned characters containing the property data.

                    For di_prop_lookup_ints(), the address to a pointer to  an
                    array of integers containing the property data.

                    For di_prop_lookup_int64(), the address to a pointer to an
                    array of 64-bit integers containing the property data.

                    For di_prop_lookup_strings(), the address to a pointer  to
                    a  buffer  containing  a  concatenation of null-terminated
                    strings containing the property data.


       prop_name    Name of the property for which to search.


DESCRIPTION
       These functions return the value of a  known  property  name  type  and
       dev_t  value. All memory allocated by these functions is managed by the
       library and must not be freed by the caller.

RETURN VALUES
       If the property is  found,  the  number  of  entries  in  prop_data  is
       returned.  If  the  property  is  a boolean type, 0 is returned and the
       existence of this property indicates the value is true.  Otherwise,  -1
       is returned and errno is set to indicate the error.


       The  ddi_prop_exists()  returns  1  if  a property, including a boolean
       property, exists, and 0 otherwise.

ERRORS
       These functions will fail if:

       EINVAL     Invalid argument.


       ENOTSUP    The snapshot contains no property information.


       ENXIO      The property does not exist; try di_prom_prop_lookup_*().
