 * This method works with the US-ASCII alphabet. If you port this
 * to e.g. EBCDIC, you need to make a small adjustment. Keep in mind,
 * that on the wire it MUST be US-ASCII, so basically all you need
 * to do is replace the constant '0' with 0x30 ;).

 *
 * \param iLenBuf Length of the caller-provided buffer.
 *
 * \param iToConv The integer to be converted.
