NAME
       di_path_prop_lookup_bytes, di_path_prop_lookup_int64s, di_path_prop_lookup_ints, di_path_prop_lookup_strings - search for a path property

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

       int di_path_prop_lookup_bytes(di_path_t path,
	    const char *prop_name);

       int di_path_prop_lookup_int64s(di_path_t path,
	    const char *prop_name);

       int di_path_prop_lookup_ints(di_path_t path,
	    const char *prop_name, char **prop_data);

       int di_path_prop_lookup_strings(di_path_t path,
	    const char *prop_name, char **prop_data);

PARAMETERS
       path	    The handle to a path node in a di_init(3DEVINFO).

       prop_name    The name of property for which to search.

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

		    For di_path_prop_lookup_int64(), the address to a pointer to an array of 64-bit integers containing the property data.

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

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

DESCRIPTION
       These functions return the value of a known property name and type.

       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. Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS
       These functions will fail if:

       EINVAL	  One of the arguments is invalid.

       ENOTSUP	  The snapshot contains no property information.

       ENXIO	  The path property does not exist.
