If <code>NULL</code>, then 45 * <code>u_getDataDirectory</code> is used. 46 * @param type A string that specifies the type of data to be written. 47 * For example, resource bundles are written with type "res", 48 * conversion tables with type "cnv". 49 * This may be <code>NULL</code> or empty. 50 * @param name A string that specifies the name of the data. 51 * @param pInfo A pointer to a correctly filled <code>UDataInfo</code> 52 * structure that will be copied into the file. 53 * @param comment A string (e.g., a copyright statement) that will be 54 * copied into the file if it is not <code>NULL</code> 55 * or empty.
