NAME

       RkMapRoma - perform Romaji-kana conversion by using a specified Romaji-kana conversion table

SYNOPSIS

       #include <canna/RK.h>
       int RkMapRoma(romaji, dst, maxdst, src, srclen, flags, status)
       struct RkRxDic *romaji;
       unsigned char *dst;
       int maxdst;
       unsigned char *src;
       int srclen;
       int flags;
       int *status;

DESCRIPTION

       RkMapRoma performs Romaji-kana conversion by using a specified Romaji-kana conversion table.  romaji specifies a pointer to the Romaji-kana
       conversion table that has been returned by RkOpenRoma(3).  RkMapRoma interprets the srclen bytes of contiguous data starting  at  the  area
       src  as a Romaji character string and searches through the Romaji-kana conversion table for the rule of Romaji-kana conversion that matches
       the beginning of the Romaji character string.  If the corresponding conversion rule is found, the corresponding kana  character	string	is
       stored in the area dst.	The resulting character string is truncated when its byte length exceeds maxdst -1.  dst is padded with null char-
       acters at the end if possible.

       flags is a combination of the following Romaji-kana conversion flags connected by or:

	      RK_SOKUON      Enables gemination, in which a sequence of two occurrences of the same character, xx,  is	converted  to  small  kana
			     character "tsu" only if it is not defined in the Romaji-kana conversion table file.

	      RK_FLUSH	     Converts all Romaji characters compulsorily.  Useful for handling n appearing at the end of a character string.

       The  flags  listed  below  specify  the type of characters stored in src.  These specified code conversion to be performed on the character
       string derived from the Romaji-kana conversion table.  These flags can use one by one.

	      RK_NFER	     No conversion

	      RK_XFER	     Hiragana

	      RK_HFER	     Single-byte character

	      RK_KFER	     Katakana

	      RK_ZFER	     Double-byte character

       status is set to the byte length of the character string set in the area dst.  A negative value means that  there  is  no  matching  Romaji
       character string.

RETURN VALUE

       This function returns the starting byte length of the Romaji character string matched by Romaji-kana conversion.

NAME

       wcsrtombs() - convert a wide-character string to a character string (restartable)

SYNOPSIS

DESCRIPTION

       The  function  converts	a sequence of wide-characters from the array indirectly pointed to by src into a sequence of corresponding charac-
       ters, beginning in the conversion state described by the object pointed to by ps.  If dst is not a null pointer, the  converted	characters
       are  then  stored  into	the array pointed to by dst.  Conversion continues up to and including a terminating null wide-character, which is
       also stored. Conversion stops earlier in the following cases:

       o  When a code is reached that does not correspond to a valid character.

       o  When the next character would exceed the limit of len total bytes to be stored in the array pointed to by dst (and dst  is  not  a  null
	  pointer).

       Each conversion takes place as if by a call to the function.

       If dst is not a null pointer, the pointer object pointed to by src is assigned either a null pointer (if conversion stopped due to reaching
       a terminating null wide-character) or the address just past the last wide-character converted (if  any).   If  conversion  stopped  due	to
       reaching a terminating null wide-character, the resulting state described is the initial conversion state.

       If  ps  is  a  null  pointer,  the function uses its own internal object, which is initialized at program startup to the initial conversion
       state.  Otherwise, the object pointed to by ps is used to completely describe the current conversion  state  of	the  associated  character
       sequence.  The implementation will behave as if no function defined in this specification calls

APPLICATION USAGE

       The prototype of this function is available to applications if they are:

	      a. conformant.

	      b. Compiled with macro with a value >=500.

	      c. Compiled with macro with a value >= 200112.

EXTERNAL INFLUENCES

   Environment Variables
       The behavior of this function is affected by the category of the current locale.

RETURN VALUE

       If  conversion  stops because a code is reached that does not correspond to a valid character, an encoding error occurs.  In this case, the
       function stores the value of the macro in and returns (size_t)-1; the conversion state is undefined.  Otherwise, it returns the	number	of
       bytes in the resulting character sequence, not including the terminating null (if any).

ERRORS

       The function may fail if:

	      A wide-character code does not correspond to a valid character.

	      ps	     points to an object that contains an invalid conversion state.
