LMDATA (Windows Embedded CE 6.0)

  • [アーティクル]

1/6/2010

This structure is used by the IIMCallback2::SendAlternatives2 interface to send information from an input method (IM) to an input method editor (IME).

Syntax

typedef struct  _tagLMDATA{
  DWORD dwVersion;
  DWORD flags;
  DWORD cnt;
  DWORD dwOffsetSymbols;
  DWORD dwOffsetSkip;
  DWORD dwOffsetScore;
}LMDATA;

Members

  • dwVersion
    Version number of the structure. This must be set to 0x00010000.

  • flags
    Flags to apply to the structure. This notifies the IME what kind of data a given offset type — symbol, skip, or score — contains. The following table lists the flags. This member is set to a combination of flags, with one flag for each offset type.

    Flag Description

    LMDATA_SYMBOL_BYTE

    Symbol information store as a BYTE.

    LMDATA_SYMBOL_WORD

    Symbol information store as a WORD.

    LMDATA_SYMBOL_DWORD

    Symbol information store as a DWORD.

    LMDATA_SYMBOL_QWORD

    Symbol information store as a QUAD WORD.

    LMDATA_SKIP_BYTE

    Skip information store as a BYTE.

    LMDATA_SKIP_WORD

    Skip information store as a WORD.

    LMDATA_SCORE_BYTE

    Score information store as a BYTE.

    LMDATA_SCORE_WORD

    Score information store as a WORD.

    LMDATA_SCORE_DWORD

    Score information store as a DWORD.

    LMDATA_SCORE_QWORD

    Score information store as a QUAD WORD.

    LMDATA_SCORE_FLOAT

    Score information store as a FLOAT.

    LMDATA_SCORE_DOUBLE

    Score information store as a DOUBLE.

    The skip flag is not required by the structure.

  • cnt
    Number of rows of data. A row consisting of a symbol, a score, and optionally a skip. For each symbol sent there is a score and perhaps a skip that form a row.
  • dwOffsetSymbols
    Offset to the start of the symbol table. The offset is from the end of the LMDATA structure.
  • dwOffsetSkip
    Offset to the start of the skip table. The offset is from the end of the LMDATA structure.
  • dwOffsetScore
    Offset to the start of the score table. The offset is from the end of the LMDATA structure.

Remarks

The description of the LMDATA structure can vary from application to application. For example, if the symbol being sent is really a word then the symbol table can be used as an offset to the actual word. This implementation depends completely on the how an IME and IM have agreed to share data.

In the following code example, a memory dump is shown for a structure that contains WORD symbols and a score only.
