示例1: insertResourceAfter
// Inserts "rResource" into the flow graph downstream of the
// designated "rUpstreamResource" resource.
// The new resource will be inserted on the "outPortIdx" output
// link of "rUpstreamResource".
// If the flow graph is not "started", this call takes effect
// immediately. Otherwise, the call takes effect at the start of the
// next frame processing interval.
// Returns OS_SUCCESS if the resource was successfully inserted. Returns
// OS_INVALID_ARGUMENT if the caller specified an invalid port index.
