|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.
-2 - The whole item is added to the end of the data block. The size of the data bloc is then increased by the written item.
-4 - The internal automatic position is used (see the AutoOffset property). It points behind the last read or written value.
This operation shifts the internal automatic position behind the read/written value.
If the items are read/written one by one then it is not necessary to define the position manually, but it is better to use this automated positioning.
|oBuff||(Object) Data block in the form of the PmBuffer object that is being written.|
var oBuf = Pm.CreatePmBuffer();
var s1 = "4030201060";
var nSize = oBuf.GetBuffer(); // nSize = 7
var oBuf2 = Pm.CreatePmBuffer();
var s2 = "5070";
oBuf.SetSize(nSize + 2, true);
var val = oBuf.GetHexaString(); // val = "40302010605070"
