134.Sh DESCRIPTION
135The
136.Nm prop_array_util
137family of functions are provided to make getting and setting values in
138arrays more convenient in some applications.
139.Pp
140The getters check the type of the returned object and, in some cases, also
141ensure that the returned value is within the range implied by the getter's
142value type.
143.Pp
144The setters handle object creation and release for the caller.
145.Pp
146The
147.Fn prop_array_get_cstring
148function returns dynamically allocated memory.
149See
150.Xr prop_string 3
151for more information.
152.Pp
153The
154.Fn prop_array_get_cstring_nocopy
155and
156.Fn prop_array_set_cstring_nocopy
157functions do not copy the string that is set or returned.
158See
159.Xr prop_string 3
160for more information.
161.Sh RETURN VALUES
162The
163.Nm prop_array_util
164getter functions return
165.Dv true
166if the object exists in the array and the value is in-range, or
167.Dv false
168otherwise.
169.Pp
170The
171.Nm prop_array_util
172setter functions return
173.Dv true
174if creating the object and storing it in the array is successful, or
175.Dv false
176otherwise.
