RKCVTHAN(3)RKCVTHAN(3)NAMERkCvtHan / RkwCvtHan - convert double-width symbols, alphanumeric char‐
acters, 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;
DESCRIPTIONRkCvtHan 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 bound‐
aries 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.
