di_prop_lookup_bytes(DeviceFInformation Library di_prop_lookup_bytes(3DEVINFO)

NAME
       di_prop_lookup_bytes,	 di_prop_lookup_ints,	 di_prop_lookup_int64,
       di_prop_lookup_strings - 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);

PARAMETERS
       dev	       dev_t of minor node with which the property is  associ‐
		       ated.  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
		       associated.

       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-termi‐
		       nated 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.

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_*().
