RTDLL

Description

This example program demonstrates how to use an RTDLL in an RTSS Process. It uses library functionality to provide an application similar to the DLL sample.

Source Files

The Rtdll example includes three projects, available from the VS2010 or VS2012 folder:

• SampleRtDll_<Visual Studio version>.vcxproj builds SampleRtdll.Rtdll which is an RTDLL that contains the function "Toggle" which toggles the state of the speaker.
• ExplicitLoadRtdll_<Visual Studio version>.vcproj builds ExplicitLoadRtdll.c that loads an RTDLL, calls an RTDLL function, and then frees the RTDLL. It can be built as as either a Win32 .exe binary, or an .rtss binary.
• ImplicitLoadRtdll_<Visual Studio version>.vcproj builds ImplicitLinkdll.c. This is compiled with where in the project settings the .rtdll is linked in, then through an import command we define the toggle function and run the toggle through the RTSS we just called.

The Source folder contains three source files:

• explicitlyUsingRtdll.c
• implicitlyUsingRtdll.c
• sampleRtdll.c
