       int di_prop_type(di_prop_t prop);

PARAMETERS
       prop         Handle to a property returned by di_prop_next(3DEVINFO).


       prop_data    For  di_prop_bytes(),  the  address  of  a  pointer  to an
                    unsigned character.

                    For di_prop_ints(), the address of a pointer to  an  inte‐
                    ger.

                    For  di_prop_int64(), the address of a pointer to a 64-bit
                    integer.

                    For di_prop_strings(), the address of pointer to a charac‐
                    ter.


DESCRIPTION
       These  functions access information associated with property values and
       attributes. All memory allocated by these functions is managed  by  the
       library and must not be freed by the caller.


       The  di_prop_bytes()  function returns the property data as a series of
       unsigned characters.


       The di_prop_devt() function returns the dev_t with which this  property
       is  associated.  If  the  value  is DDI_DEV_T_NONE, the property is not
       associated with any specific minor node.


       The di_prop_ints() function returns the property data as  a  series  of
       integers.


       The  di_prop_int64()  function returns the property data as a series of
       64-bit integers.


       The di_prop_name() function returns the name of the property.


       The di_prop_strings() function returns the property data as a  concate‐
       nation of null-terminated strings.


       The  di_prop_type() function returns the type of the property. The type
       determines the appropriate interface to  access  property  values.  The
       following is a list of possible types:

       DI_PROP_TYPE_BOOLEAN     There  is  no interface to call since there is
                                no property data associated with boolean prop‐
                                erties.  The existence of the property defines
                                a TRUE value.


       DI_PROP_TYPE_INT         Use di_prop_ints() to access property data.


       DI_PROP_TYPE_INT64       Use di_prop_int64() to access property data.


       DI_PROP_TYPE_STRING      Use di_prop_strings() to access property data.


       DI_PROP_TYPE_BYTE        Use di_prop_bytes() to access property data.


       DI_PROP_TYPE_UNKNOWN     Use di_prop_bytes() to access  property  data.
                                Since  the  type  of  property is unknown, the
                                caller is  responsible  for  interpreting  the
                                contents of the data.


       DI_PROP_TYPE_UNDEF_IT    The property has been undefined by the driver.
                                No property data is available.


RETURN VALUES
       Upon   successful    completion,    di_prop_bytes(),    di_prop_ints(),
       di_prop_int64(),  and  di_prop_strings()  return  a non-negative value,
       indicating the number of entries in  the  property  value  buffer.  See
       di_prom_prop_lookup_bytes(3DEVINFO)  for  a  description  of the return
       values. Otherwise, -1 is returned and errno  is  set  to  indicate  the
       error.


       The di_prop_devt() function returns the dev_t value associated with the
       property.


       The di_prop_name() function returns a pointer to  a  string  containing
       the name of the property.


       The  di_prop_type()  function  can return one of types described in the
       DESCRIPTION section.

ERRORS
       These functions will fail if:

       EINVAL    Invalid argument. For example, the  property  type  does  not
                 match the interface.
