printf() wrapper that is not sensitive to LC_NUMERIC settings. * * This function has the same contract as standard printf(), except that * formatting of floating-point numbers will use decimal point, whatever the * current locale is set. * * @param fmt formatting string * @param ... arguments * @return the number of characters (excluding terminating nul) written in * output buffer. */
