Besides of this, usermode apps can call DbgPrint, DbgPrintEx,
vDbgPrintExWithPrefix.
They are exported from ntdll.dll, though not included in the export lib.
GetProcAddress will get them.

It is possible but I believe in this case it is necessary to use kernel
mode capture in the DebugView. And verbose mode, according to functions
and filters used. The same rules as for drivers.
