+// The preprocessor directives here ensure that KSTOPOLOGY_CONNECTION is defined in the correct way
+// Constraint is that ks.h cannot be included in the idl file. The directives below ensure that
+// 1) KSTOPOLOGY_CONNECTION is locally defined for purposes of building the idl file itself.
+// 2) An app can include vidcap.h and ks.h in either order.
+// 3) The structure definition for KSTOPOLOGY_CONNECTION does not show up in vidcap.h since ks.h gets included.
+// Look at vidcap.h to understand exactly what gets generated.
