|nOffset||[optional] (Long) Specifies 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 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.
|nSize||[optional] (Long) The size of read data block.
The -1 value (default) means that the data block is read from the defined starting position to the end.
|nAttr||[optional] (Long) Specifies how the HexaString is generated.
0 (default) - The hexa characters will be lowercase.
1 - The hexa characters will be uppercase.
var b = Pm.CreatePmBuffer();
var s = b.GetHexaString(); // The result will be a HexaString "40302010605070"
