142.Sh DESCRIPTION
143The
144.Nm prop_dictionary_util
145family of functions are provided to make getting and setting values in
146dictionaries more convenient in some applications.
147.Pp
148The getters check the type of the returned object and, in some cases, also
149ensure that the returned value is within the range implied by the getter's
150value type.
151.Pp
152The setters handle object creation and release for the caller.
153.Pp
154The
155.Fn prop_dictionary_get_cstring
156function returns dynamically allocated memory.
157See
158.Xr prop_string 3
159for more information.
160.Pp
161The
162.Fn prop_dictionary_get_cstring_nocopy
163and
164.Fn prop_dictionary_set_cstring_nocopy
165functions do not copy the string that is set or returned.
166See
167.Xr prop_string 3
168for more information.
169.Pp
170The
171.Fn prop_dictionary_set_and_rel
172function adds the object to the dictionary and releases it.
173The object is also released on failure.
174.Sh RETURN VALUES
175The
176.Nm prop_dictionary_util
177getter functions return
178.Dv true
179if the object exists in the dictionary and the value is in-range, or
180.Dv false
181otherwise.
182.Pp
183The
184.Nm prop_dictionary_util
185setter functions return
186.Dv true
187if creating the object and storing it in the dictionary is successful, or
188.Dv false
189otherwise.
