Как правильно оспользывать эти значения?

/* Gets info from player. */
native get_user_info(index,const info[],output[],len);

/* Fills string with given format and parameters.
* Function returns number of copied chars.
* Example: format(dest,"Hello %s. You are %d years old","Tom",17).
* If any of your input buffers overlap with the destination buffer,
*  format() falls back to a "copy-back" version as of 1.65.  This is
*  slower, so you should using a source string that is the same as
*  the destination.
