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