voidEmitStreamVertex(intstream);

AvailableonlyintheGeometryShader, EmitStreamVertex emits the current values of output variables to
       the current output primitive on stream stream. The argument stream must be a constant integral
       expression. On return from this call, the value of all output variables for all streams are undefined.

stream
           Specifies the stream upon which the vertex will be emitted.
