"RKCVTHAN" "3"
"NAME"
\f4RkCvtHan\f1 / \f4RkwCvtHan\f1 - 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"
\f2RkCvtHan\f1 converts the \f2srclen\f1 bytes of double-width symbol, alphanumeric characters, hiragana, and katakana data to single-width characters, starting at the area \f2src\f1. A null character in \f2src\f1 is not interpreted as the end of the string. The conversion result is stored in the area \f2dst\f1. 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 \f2maxdst\f1 -1. \f2dst\f1 is padded with null characters at the end if possible. EUC code is used to represent both \f2src\f1 and \f2dst\f1.
\f2RkwCvtHan\f1 is the wchar_t version of \f2RkCvtHan\f1. Arguments which specify the length are regarded as they count the character length instead of byte length.
\f4NULL\f1 can be specified in \f2dst\f1. \f4NULL\f1 overrides the entire conversion result.
"RETURN VALUE"
This function returns the byte length (or character length for RkwCvtHan) of the conversion result, or returns \f40\f1 if the value of \f2maxdst\f1 is invalid.
