This model illustrates how a C style pointer may be passed between two EmbeddedCActors. To see the C code definition of each actor, right click and select "Look Inside" Note that each actor has an "ptr" output port that passes a pointer. This model is identical to SimplePassPointer.xml except that it utilizes the embeddedCFileActor rather than the embeddedCActor. The C code is located in the following two files: ptolemy/actor/lib/jni/demo/SimplePassPointer/mallocCode.c ptolemy/actor/lib/jni/demo/SimplePassPointer/codeForSimplePassPointerWithECFA.c
