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