How to get psltscale system variables of the specified layout

[adn019LKFW]

In the example drawing, psltscale of "layout1" is 1, and psltscale of "layout2" is 0. What is the correct way to get the psltscale in the specified layout. Function AcDbDatabase::psltscale() does not provide parameter for specifying layout or modelspace.

I think the only possible way without switching the layout is to analyze the DXF data of the AcDbLayout.

Here are screenshots of ArxDbg's command SNOOPDB:

You can retrieve the DXF resbuf list like this:

AcDbDatabase *pDB = acdbHostApplicationServices()->workingDatabase();
AcDbObjectId idLayoutDict(pDB->layoutDictionaryId());
ads_name dict;
acdbGetAdsName(dict, idLayoutDict);

struct resbuf* rb = acdbDictSearch(dict, L"Layout1", 0);
if (rb)	{
	// find 100, "AcDbLayout", 1, "Layout1", 70 and get the int value
	acutRelRb(rb);
}
