Value = PmBuffer.GetBit(nOffset, nBitIndex)
|nOffset||(Long) Defines the position of read value in the data block. |
The read value must be inside the data block. The item is read 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 AutoOffset). 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 handy 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).|
