Description

Invalid Stream

The Invalid Stream block outputs an invalid stream. This block is typically used with the FIFO Read block to pass a stream (t_stream_ptr) between two asynchronous threads. In this case, the FIFO Read block's Action to take on underflow parameter must be set to "use external input" and the def input should be the output of an Invalid Stream block.

Input Ports

This block has no input ports.

Output Ports

stm

A reference to an invalid stream.

Data Type Support

The Invalid Stream block outputs a t_stream_ptr.

Parameters and Dialog Box

Invalid Stream

The Invalid Stream block has no parameters.
