NAME

       RkCvtZen - convert ASCII characters and single-width katakana to double-width characters

SYNOPSIS

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

DESCRIPTION

       RkCvtZen  converts  the  srclen  bytes  of ASCII character and single-width katakana data to double-width
       character, 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.

RETURN VALUE

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