18 RkCvtZen converts the srclen bytes of ASCII character and single-width
19 katakana data to double-width character, starting at the area src. A
20 null character in src is not interpreted as the end of the string. The
21 conversion result is stored in the area dst. Characters that are not
22 subject to conversion are copied as they area. The conversion result
23 is truncated to adjust to character boundaries in the EUC code when its
24 byte length exceeds maxdst -1. dst is padded with null characters at
25 the end if possible. EUC code is used to represent both src and dst.
26
27 NULL can be specified in dst. NULL overrides the entire conversion
28 result.
29
31 This function returns the byte length of the conversion result, or
32 returns 0 if the value of maxdst is invalid.
