Force single object selection only - acedSSGet ":S"

[Anonymous]

I force acedSSGet() func to get only one object with ":S".   
like this:
acedSSGet(_T("_:S"), NULL, NULL, rb, sset);

but It does't work . I  can still select more than one Entities.
Can someone help me or Give a sample code ?

Thanks in advance.

int rc = acedSSGet(_T("_+.:S"), NULL, NULL, rb, sset);
这样可以选择单个实体.
