BLOB_NAME_LENGTH_STATUS
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 length and status of the BLOB data column.
BLOB_NAME_LENGTH_STATUS(pszName, IID, flags, data, length, 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.length
[out] The (actual) length in bytes of the BLOB column.status
[out] The status of the BLOB field.
