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 

     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 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.

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.
