NAME

       RkCvtHan  /  RkwCvtHan  - convert double-width symbols, alphanumeric characters, 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, 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
       are.  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.

       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.

                                                                                      RKCVTHAN(3)
