|nOffset||(Long) Specifies the position of written value in the data block.
The whole written item muyst be inside the data block, or the whole item is added to the end of the data block. The item is written either whole or not read at all.
>= 0 - Index (in bytes, zero-based index) in data block.
-4 - The internal automatic position is used (see the AutoOffset property). It points behind the last read or written value and increases continually.
If the items are read/written one by one then it is not necessary to define the position, but it is better to use this automated positioning.
|nBitIndex||(Long) Bit index (zero-based index). The value must be any non-negative integer (it must define the position inside the data area range).|
|bValue||(Boolean) Written value.|
