    plRetVal : int
) : int

Parameters

  • HIMC
    Type: UInt32

    [in] Handle to the IME context.

  • dwIndex
    Type: UInt32

    [in] Index of the information to retrieve. For more information about possible values, see IME Composition String Values.

  • pbstrCompString
    Type: String%

    [out] Binary buffer—not a Unicode string. Allocated using SysAllocStringByteLen. For more information, see ImmSetCompositionString

    and ImmGetCompositionString.

  • plRetVal
    Type: Int32%

    [out] Pointer to the return value. Contains the number of bytes copied to the destination buffer or, if dwBufLen is zero, the buffer size, in bytes, needed to receive all of the information. The size is always in bytes, even if the requested data is a Unicode string.

    On error, set to one of the two values: IMM_ERROR_NODATA, or IMM_ERROR_GENERAL.

Return Value

Type: Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

COM Signature

From vsshell.idl:

   [in] DWORD dwIndex, 
   [out] BSTR *pbstrCompString, 
   [out] LONG * plRetVal
);
