/**
 * Create a new binary data file.
 * The file-writing <code>udata_</code> functions facilitate writing
 * binary data files that can be read by ICU's <code>udata</code> API.
 * This function opens a new file with a filename determined from its
 * parameters - of the form "name.type".
 * It then writes a short header, followed by the <code>UDataInfo</code>
 * structure and, optionally, by the comment string.
 * It then writes padding bytes to round up to a multiple of 16 bytes.
 * Subsequent write operations will thus start at an offset in the file
 * that is a multiple of 16. <code>udata_getMemory()</code> will return
 * a pointer to this same starting offset.
 *
 * See udata.h .
 *
 * @param dir A string that specifies the directory where the data will be
 *            written. If <code>NULL</code>, then
 *            <code>u_getDataDirectory</code> is used.
 * @param type A string that specifies the type of data to be written.
 *             For example, resource bundles are written with type "res",
 *             conversion tables with type "cnv".
 *             This may be <code>NULL</code> or empty.
 * @param name A string that specifies the name of the data.
 * @param pInfo A pointer to a correctly filled <code>UDataInfo</code>
 *              structure that will be copied into the file.
 * @param comment A string (e.g., a copyright statement) that will be
 *                copied into the file if it is not <code>NULL</code>
 *                or empty. This string serves only as a comment in the binary
 *                file. It will not be accessible by any API.
 * @param pErrorCode An ICU UErrorCode parameter. It must not be <code>NULL</code>.
