NAME
     RkCvtHan  /  RkwCvtHan - convert double-width symbols, alphanumeric charac-
     ters, hiragana, and katakana to single-width characters

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

DESCRIPTION
     RkCvtHan converts the srclen bytes  of  double-width  symbol,  alphanumeric
     characters,  hiragana, and katakana data to single-width characters, start-
     ing 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.	 Charac-
     ters  that  are not subject to conversion are copied as they are.	The con-
     version result is truncated to adjust to character boundaries  in	the  EUC
     code when its byte length exceeds maxdst -1.  dst is padded with null char-
     acters  at the end if possible.  EUC code is used to represent both src and
     dst.

     RkwCvtHan is the wchar_t version of RkCvtHan.  Arguments which specify  the
     length  are  regarded  as	they  count the character length instead of byte
     length.

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

RETURN VALUE
     This function returns the byte length (or character length  for  RkwCvtHan)
     of the conversion result, or returns 0 if the value of maxdst is invalid.
