 * Formatted output functions.
 *
 * The functions provided by this module implement a subset of the C99
 * printf() like functions, mostly centered around character, string, and
 * integer conversions.
 *
 * The supported specifiers are: d i o u x X c s p n %
 * The supported length modifiers are: hh h l ll z t
 *
 * The xprintf() and xvprintf() functions internally use a statically
 * allocated buffer. Although they are thread-safe, they won't produce
 * output larger than 1 KiB.
