       RkMapRoma  -  perform  Romaji-kana  conversion by using a specified Romaji-kana conversion


       #include <canna/RK.h>
       int RkMapRoma(romaji, dst, maxdst, src, srclen, flags, status)
       struct RkRxDic *romaji;
       unsigned char *dst;
       int maxdst;
       unsigned char *src;
       int srclen;
       int flags;
       int *status;


       RkMapRoma performs Romaji-kana conversion by  using  a  specified  Romaji-kana  conversion
       table.   romaji  specifies  a  pointer  to  the Romaji-kana conversion table that has been
       returned by RkOpenRoma(3).  RkMapRoma interprets  the  srclen  bytes  of  contiguous  data
       starting at the area src as a Romaji character string and searches through the Romaji-kana
       conversion table for the rule of Romaji-kana conversion that matches the beginning of  the
       Romaji character string.  If the corresponding conversion rule is found, the corresponding
       kana character string is stored in the  area  dst.   The  resulting  character  string  is
       truncated  when  its byte length exceeds maxdst -1.  dst is padded with null characters at
       the end if possible.

       flags is a combination of the following Romaji-kana conversion flags connected by or:

              RK_SOKUON      Enables gemination, in which a sequence of two  occurrences  of  the
                             same  character, xx, is converted to small kana character "tsu" only
                             if it is not defined in the Romaji-kana conversion table file.

              RK_FLUSH       Converts all Romaji characters compulsorily.  Useful for handling  n
                             appearing at the end of a character string.

       The flags listed below specify the type of characters stored in src.  These specified code
       conversion to be performed on the character string derived from the Romaji-kana conversion
       table.  These flags can use one by one.

              RK_NFER        No conversion

              RK_XFER        Hiragana

              RK_HFER        Single-byte character

              RK_KFER        Katakana

              RK_ZFER        Double-byte character

       status  is set to the byte length of the character string set in the area dst.  A negative
       value means that there is no matching Romaji character string.


       This function returns the starting byte length of the Romaji character string  matched  by
       Romaji-kana conversion.
