     prop_object_equals, prop_object_iterator_next,
     prop_object_iterator_reset, prop_object_iterator_release -- general prop-
     erty container object functions

LIBRARY
     Property Container Object Library (libprop, -lprop)

SYNOPSIS
     #include <prop/proplib.h>

     void
     prop_object_retain(prop_object_t obj);

     void
     prop_object_release(prop_object_t obj);

     prop_type_t
     prop_object_type(prop_object_t obj);

     bool
     prop_object_equals(prop_object_t obj1, prop_object_t obj2);

     prop_object_t
     prop_object_iterator_next(prop_object_iterator_t iter);

     void
     prop_object_iterator_reset(prop_object_iterator_t iter);

     void
     prop_object_iterator_release(prop_object_iterator_t iter);

DESCRIPTION
     The prop_object family of functions operate on all property container
     object types.

     prop_object_retain(prop_object_t obj)
       Increment the reference count on an object.

     prop_object_release(prop_object_t obj)
       Decrement the reference count on an object.  If the last reference is
       dropped, the object is freed.

     prop_object_type(prop_object_t obj)
       Determine the type of the object.  Objects are one of the following
       types:

       PROP_TYPE_BOOL         Boolean value (prop_bool_t)
       PROP_TYPE_NUMBER       Number (prop_number_t)
       PROP_TYPE_STRING       String (prop_string_t)
       PROP_TYPE_DATA         Opaque data (prop_data_t)
       PROP_TYPE_ARRAY        Array (prop_array_t)
       PROP_TYPE_DICTIONARY   Dictionary (prop_dictionary_t)
       PROP_TYPE_DICT_KEYSYM  Dictionary key symbol (prop_dictionary_keysym_t)

       If obj is NULL, then PROP_TYPE_UNKNOWN is returned.

     prop_object_equals(prop_object_t obj1, prop_object_t obj2)
       Returns true if the two objects are of the same type and are equiva-
       lent.

     prop_object_iterator_next(prop_object_iterator_t iter)
       Return the next object in the collection (array or dictionary) being
       iterated by the iterator iter.  If there are no more objects in the
       collection, NULL is returned.

     prop_object_iterator_reset(prop_object_iterator_t iter)
       Reset the iterator to the first object in the collection being iterated
       by the iterator iter.

     prop_object_iterator_release(prop_object_iterator_t iter)
       Release the iterator iter.
