BLOB_NAME_STATUS

  • Article

Used with BEGIN_COLUMN_MAP and END_COLUMN_MAP to bind a binary large object (BLOB). Similar to BLOB_NAME, except that this macro also gets the status of the BLOB data column.

BLOB_NAME_STATUS(pszName, IID, flags, data, status )

Parameters

  • pszName
    [in] A pointer to the column name. The name must be a Unicode string. You can accomplish this by putting an 'L' in front of the name, for example: L"MyColumn".

  • IID
    [in] Interface GUID, such as IDD_ISequentialStream, used to retrieve the BLOB.

  • flags
    [in] Storage-mode flags as defined by the OLE Structured Storage model (for example, STGM_READ).

  • data
    [in] The corresponding data member in the user record.

  • status
    [out] The status of the BLOB field.
