- * \brief C API: DateFormat
- *
- * <h2> Date Format C API</h2>
- *
- * Date Format C API  consists of functions that convert dates and
- * times from their internal representations to textual form and back again in a
- * language-independent manner. Converting from the internal representation (milliseconds
- * since midnight, January 1, 1970) to text is known as "formatting," and converting
- * from text to millis is known as "parsing."  We currently define only one concrete
- * structure UDateFormat, which can handle pretty much all normal
- * date formatting and parsing actions.
- * <P>
- * Date Format helps you to format and parse dates for any locale. Your code can
- * be completely independent of the locale conventions for months, days of the
- * week, or even the calendar format: lunar vs. solar.
- * <P>
- * To format a date for the current Locale with default time and date style,
- * use one of the static factory methods:
- * <pre>
- * \code
- *  UErrorCode status = U_ZERO_ERROR;
- *  UChar *myString;
- *  int32_t myStrlen = 0;
- *  UDateFormat* dfmt = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, NULL, -1, NULL, -1, &status);
- *  myStrlen = udat_format(dfmt, myDate, NULL, myStrlen, NULL, &status);
- *  if (status==U_BUFFER_OVERFLOW_ERROR){
- *      status=U_ZERO_ERROR;
- *      myString=(UChar*)malloc(sizeof(UChar) * (myStrlen+1) );
- *      udat_format(dfmt, myDate, myString, myStrlen+1, NULL, &status);
- *  }
- * \endcode
- * </pre>
- * If you are formatting multiple numbers, it is more efficient to get the
- * format and use it multiple times so that the system doesn't have to fetch the
- * information about the local language and country conventions multiple times.
- * <pre>
- * \code
- *  UErrorCode status = U_ZERO_ERROR;
- *  int32_t i, myStrlen = 0;
- *  UChar* myString;
- *  char buffer[1024];
- *  UDate myDateArr[] = { 0.0, 100000000.0, 2000000000.0 }; // test values
- *  UDateFormat* df = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, NULL, -1, NULL, 0, &status);
- *  for (i = 0; i < 3; i++) {
- *      myStrlen = udat_format(df, myDateArr[i], NULL, myStrlen, NULL, &status);
- *      if(status == U_BUFFER_OVERFLOW_ERROR){
- *          status = U_ZERO_ERROR;
- *          myString = (UChar*)malloc(sizeof(UChar) * (myStrlen+1) );
- *          udat_format(df, myDateArr[i], myString, myStrlen+1, NULL, &status);
- *          printf("%s\n", u_austrcpy(buffer, myString) );
- *          free(myString);
- *      }
- *  }
- * \endcode
- * </pre>
- * To get specific fields of a date, you can use UFieldPosition to
- * get specific fields.
- * <pre>
- * \code
- *  UErrorCode status = U_ZERO_ERROR;
- *  UFieldPosition pos;
- *  UChar *myString;
- *  int32_t myStrlen = 0;
- *  char buffer[1024];
- *
- *  pos.field = 1;  // Same as the DateFormat::EField enum
- *  UDateFormat* dfmt = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, -1, NULL, 0, &status);
- *  myStrlen = udat_format(dfmt, myDate, NULL, myStrlen, &pos, &status);
- *  if (status==U_BUFFER_OVERFLOW_ERROR){
- *      status=U_ZERO_ERROR;
- *      myString=(UChar*)malloc(sizeof(UChar) * (myStrlen+1) );
- *      udat_format(dfmt, myDate, myString, myStrlen+1, &pos, &status);
- *  }
- *  printf("date format: %s\n", u_austrcpy(buffer, myString));
- *  buffer[pos.endIndex] = 0;   // NULL terminate the string.
- *  printf("UFieldPosition position equals %s\n", &buffer[pos.beginIndex]);
- * \endcode
- * </pre>
- * To format a date for a different Locale, specify it in the call to
- * udat_open()
- * <pre>
- * \code
- *        UDateFormat* df = udat_open(UDAT_SHORT, UDAT_SHORT, "fr_FR", NULL, -1, NULL, 0, &status);
- * \endcode
- * </pre>
- * You can use a DateFormat API udat_parse() to parse.
- * <pre>
- * \code
- *  UErrorCode status = U_ZERO_ERROR;
- *  int32_t parsepos=0;
- *  UDate myDate = udat_parse(df, myString, u_strlen(myString), &parsepos, &status);
- * \endcode
- * </pre>
- *  You can pass in different options for the arguments for date and time style
- *  to control the length of the result; from SHORT to MEDIUM to LONG to FULL.
- *  The exact result depends on the locale, but generally:
- *  see UDateFormatStyle for more details
- * <ul type=round>
- *   <li>   UDAT_SHORT is completely numeric, such as 12/13/52 or 3:30pm
- *   <li>   UDAT_MEDIUM is longer, such as Jan 12, 1952
- *   <li>   UDAT_LONG is longer, such as January 12, 1952 or 3:30:32pm
- *   <li>   UDAT_FULL is pretty completely specified, such as
- *          Tuesday, April 12, 1952 AD or 3:30:42pm PST.
- * </ul>
- * You can also set the time zone on the format if you wish.
- * <P>
- * You can also use forms of the parse and format methods with Parse Position and
- * UFieldPosition to allow you to
- * <ul type=round>
- *   <li>   Progressively parse through pieces of a string.
- *   <li>   Align any particular field, or find out where it is for selection
- *          on the screen.
- * </ul>
