NAME
       RRkkCCvvttZZeenn - convert ASCII characters and single-width katakana to
       double-width characters

SYNOPSIS
       ##iinncclluuddee <<ccaannnnaa//RRKK..hh>>
       iinntt RRkkCCvvttZZeenn((ddsstt,, mmaaxxddsstt,, ssrrcc,, ssrrcclleenn))

       iinntt ssrrcclleenn;;

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.

       NNUULLLL can be specified in dst.  NNUULLLL overrides the entire conversion
       result.

RETURN VALUE
       This function returns the byte length of the conversion result, or
       returns 00 if the value of maxdst is invalid.
