Virtual Source

When paired with a Virtual Sink block, this is essentially the same as drawing a wire between two blocks. This block can be useful for tidying up a complex flowgraph. This block does not support C++ output, so it cannot be used when the output language of a flowgraph in GRC is C++.


Stream ID
Specifies the stream ID of the virtual sink to read from. To link the stream with a virtual sink, the same value of stream ID must be set in the corresponding source and sink blocks.
