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.
