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.
