# DESCRIPTION

The prop_array_util family of functions are provided to make getting and setting values in arrays more convenient in some applications.

The getters check the type of the returned object and, in some cases, also ensure that the returned value is within the range implied by the getter's value type.

The setters handle object creation and release for the caller.

The prop_array_get_cstring() function returns dynamically allocated memory. See prop_string(3) for more information.

The prop_array_get_cstring_nocopy() and prop_array_set_cstring_nocopy() functions do not copy the string that is set or returned. See prop_string(3) for more information.

The prop_array_add_and_rel() function adds the object to the end of the array and releases it. The object is also released on failure.

# RETURN VALUES

The prop_array_util getter functions return true if the object exists in the array and the value is in-range, or false otherwise.

The prop_array_util setter functions return true if creating the object and storing it in the array is successful, or false otherwise.
