PARAMETERS
path The handle to a path node in adi_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 con-
taining 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 concate-
nation of null-terminated strings containing
the property data.SunOS 5.11 Last change: 15 May 2008 1

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.ATTRIBUTES
