From: sh192 on 2 Aug 2010 06:05 Hi, is it possible, to call a "normal" C-DLL from an UMDF driver? How may I communicate with an UMDF driver? Is it only possible to use DeviceIoControls or are there other ways? Thanks in advice, sh192

Virtually any mechanism you would use to communicate between two ordinary processes will work in a UMDF driver.
