       RkCvtKana - convert double-width hiragana to double-width katakana


       #include <canna/RK.h>
       int RkCvtKana(dst, maxdst, src, srclen)
       unsigned char *dst;
       int maxdst;
       unsigned char *src;
       int srclen;


       RkCvtKana  converts  the  srclen  bytes  of  double-width  hiragana  data  to double-width
       katakana, starting at the area src.  A null character in src is not interpreted as the end
       of  the string.  The conversion result is stored in the area dst.  Characters that are not
       subject to conversion are copied as they area.  The  conversion  result  is  truncated  to
       adjust  to  character  boundaries  in the EUC code when its byte length exceeds maxdst -1.
       dst is padded with null characters at the end if possible.  EUC code is used to  represent
       both src and dst.

       NULL can be specified in dst.  NULL overrides the entire conversion result.


       This  function returns the byte length of the conversion result, or returns 0 if the value
       of maxdst is invalid.
