     The prop_dictionary family of functions operate on the dictionary property collection object
     type.  A dictionary is an unordered set of objects stored as key-value pairs.

	    Create an empty dictionary.  The dictionary initially has no capacity.  Returns NULL
	    on failure.

     prop_dictionary_create_with_capacity(unsigned int capacity)
	    Create a dictionary with the capacity to store capacity objects.  Returns NULL on

     prop_dictionary_copy(prop_dictionary_t dict)
	    Copy a dictionary.	The new dictionary has an initial capacity equal to the number of
	    objects stored in the dictionary being copied.  The new dictionary contains refer-
	    ences to the original dictionary's objects, not copies of those objects (i.e. a
	    shallow copy is made).  If the original dictionary is immutable, the resulting dic-
	    tionary is also immutable.

     prop_dictionary_copy_mutable(prop_dictionary_t dict)
	    Like prop_dictionary_copy(), except the resulting dictionary is always mutable.

     prop_dictionary_count(prop_dictionary_t dict)
	    Returns the number of objects stored in the dictionary.

     prop_dictionary_ensure_capacity(prop_dictionary_t dict, unsigned int capacity)
	    Ensure that the dictionary has a total capacity of capacity, including objects
	    already stored in the dictionary.  Returns true if the capacity of the dictionary is
	    greater or equal to capacity or if the expansion of the dictionary's capacity was
	    successful and false otherwise.  If the supplied object isn't a dictionary, false is

     prop_dictionary_iterator(prop_dictionary_t dict)
	    Create an iterator for the dictionary.  The dictionary is retained by the iterator.
	    A dictionary iterator returns the key symbols used to look up objects stored in the
	    dictionary; to get the object itself, a dictionary lookup using this key symbol must
	    be performed.  Storing to or removing from the dictionary invalidates any active
	    iterators for the dictionary.  Returns NULL on failure.

     prop_dictionary_all_keys(prop_dictionary_t dict)
	    Return an array of all of the dictionary key symbols (prop_dictionary_keysym_t) in
	    the dictionary.  This provides a way to iterate over the items in the dictionary
	    while retaining the ability to mutate the dictionary; instead of iterating over the
	    dictionary itself, iterate over the array of keys.	The caller is responsible for
	    releasing the array.  Returns NULL on failure.

     prop_dictionary_make_immutable(prop_dictionary_t dict)
	    Make dict immutable.

     prop_dictionary_mutable(prop_dictionary_t dict)
	    Returns true if the dictionary is mutable.

     prop_dictionary_get(prop_dictionary_t dict, const char *key)
	    Return the object stored in the dictionary with the key key.  If no object is stored
	    with the specified key, NULL is returned.

     prop_dictionary_set(prop_dictionary_t dict, const char *key, prop_object_t obj)
	    Store a reference to the object obj with the key key.  The object will be retained by
	    the dictionary.  If the key already exists in the dictionary, the object associated
	    with that key will be released and replaced with the new object.  Returns true if
	    storing the object was successful and false otherwise.

     prop_dictionary_remove(prop_dictionary_t dict, const char *key)
	    Remove the reference to the object stored in the dictionary with the key key.  The
	    object will be released.

     prop_dictionary_get_keysym(prop_dictionary_t dict, prop_dictionary_keysym_t sym)
	    Like prop_dictionary_get(), but the lookup is performed using a key symbol returned
	    by a dictionary iterator.  The results are undefined if the iterator used to obtain
	    the key symbol is not associated with dict.

     prop_dictionary_set_keysym(prop_dictionary_t dict, prop_dictionary_keysym_t sym,
	    prop_object_t obj)
	    Like prop_dictionary_set(), but the lookup of the object to replace is performed
	    using a key symbol returned by a dictionary iterator.  The results are undefined if
	    the iterator used to obtain the key symbol is not associated with dict.

     prop_dictionary_remove_keysym(prop_dictionary_t dict, prop_dictionary_keysym_t sym)
	    Like prop_dictionary_remove(), but the lookup of the object to remove is performed
	    using a key symbol returned by a dictionary iterator.  The results are undefined if
	    the iterator used to obtain the key symbol is not associated with dict.

     prop_dictionary_equals(prop_dictionary_t dict1, prop_dictionary_t dict2)
	    Returns true if the two dictionaries are equivalent.  Note: Objects contained in the
	    dictionary are compared by value, not by reference.

     prop_dictionary_keysym_cstring_nocopy(prop_dictionary_keysym_t keysym)
	    Returns an immutable reference to the dictionary key symbol's string value.

     prop_dictionary_keysym_equals(prop_dictionary_keysym_t keysym1, prop_dictionary_keysym_t
	    Returns true if the two dictionary key symbols are equivalent.

     prop_dictionary_externalize(prop_dictionary_t dict)
	    Externalizes a dictionary, returning a NUL-terminated buffer containing the XML rep-
	    resentation of the dictionary.  The caller is responsible for freeing the returned
	    buffer.  If converting to the external representation fails for any reason, NULL is

	    In user space, the buffer is allocated using malloc(3).  In the kernel, the buffer is
	    allocated using malloc(9) using the malloc type M_TEMP.

     prop_dictionary_internalize(const char *xml)
	    Parse the XML representation of a property list in the NUL-terminated buffer xml and
	    return the corresponding dictionary.  Returns NULL if parsing fails for any reason.

     prop_dictionary_externalize_to_file(prop_dictionary_t dict, const char *path)
	    Externalizes a dictionary and writes it to the file specified by path.  The file is
	    saved with the mode 0666 as modified by the process's file creation mask (see
	    umask(2)) and is written atomically.  Returns false if externalizing or writing the
	    dictionary fails for any reason.

     prop_dictionary_internalize_from_file(const char *path)
	    Reads the XML property list contained in the file specified by path, internalizes it,
	    and returns the corresponding dictionary.  Returns NULL on failure.

     prop_dictionary_externalize_to_pref(prop_dictionary_t dict, struct plistref *pref)
	    Externalizes a dictionary and packs it into the plistref specified by pref.  Returns
	    false if externalizing the dictionary fails for any reason.

     prop_dictionary_internalize_from_pref(const struct plistref *pref, prop_dictionary_t *dictp)
	    Reads the plistref specified by pref, internalizes it, and returns the corresponding
	    dictionary.  Returns false if internalizing or writing the dictionary fails for any

     prop_array(3), prop_bool(3), prop_data(3), prop_dictionary_util(3), prop_number(3),
     prop_object(3), prop_string(3), proplib(3)

     The proplib property container object library first appeared in NetBSD 4.0.
