Formattable

Formattable interconverts between the primitive numeric types (double, long, etc.) as well as i18n_udate and char string.

Required Header

#include <utils_i18n.h>

Overview

Internally, an i18n_formattable_h handle holds an object that is a union of primitive types. As such, it can only store one flavor of data at a time. To determine what flavor of data it contains, use the i18n_formattable_get_type function.
