RKBGNBUN

NAME

RkBgnBun / RkwBgnBun - convert the reading of a specified length to kanji

SYNOPSIS

#include <canna/RK.h>
int RkBgnBun(cxnum, yomi, maxyomi, mode)
int cxnum;
unsigned char *yomi;
int maxyomi;
int mode;
int RkwBgnBun(cxnum, yomi, maxyomi, mode)
int cxnum;
wchar_t *yomi;
int maxyomi;
int mode;

DESCRIPTION

RkBgnBun converts the reading yomi with a length of maxyomi bytes to kanji. The reading kana must be adjusted on character boundaries in the EUC code. The context enters the conversion mode, with both the current clause and the current clause set to 0. RkwBgnBun is the similar function to RkBgnBun, but it takes wchar_t argument as yomi. maxyomi represents the length of yomi by characters instead of bytes. mode represents the code conversion candidate to be added to each clause. It is expressed in a bit field width, which can be set to one of the following with RK_XFERBITS:

RK_XFER: Hiragana
RK_HFER: Single-width character
RK_KFER: Katakana
RK_ZFER: Double-width character

If the number of candidates available for the current clause is N, candidates are added through code conversion by reading the candidates in sequence, from candidate N to candidate N + 1, and so on, starting with the lowest-order bit field. Candidate addition ends when the corresponding bit field equals 0.


mode   Candidate
RK_XFER(KANJI) (HIRAGANA)
(RK_XFER << RK_XFERBITS) | RK_KFER(KANJI) (KATAKANA) (HIRAGANA)
(RK_KFER << RK_XFERBITS) | RK_XFER(KANJI) (HIRAGANA) (KATAKANA)

The context enters the conversion mode, from RkBgnBun to RkEndBun(3). Conversion modes cannot be nested.

RETURN VALUE

This function returns the number of clauses derived from conversion, or returns -1 if the conversion fails.
