—Set the Streaming Waveform
Handle property or the
NIFGEN_ATTR_STREAMING_WAVEFORM_HANDLE
attribute to the
waveform handle returned in step 1. Setting this property or attribute
ensures that none of your streaming data is overwritten before it is
generated. NI-FGEN monitors your progress to ensure that you write
fresh data fast enough to keep up with the generation. If your
application fails to keep up or attempts to write fresh data over data that
has not been generated, NI-FGEN returns an error.
