Function Usage

The term waveform/pattern output is used extensively throughout the entries for the
functions of the form daqDac…. This refers to an analog waveform output modes and/or
digital pattern output modes. These terms describe output to digital-to-analog converter
(DAC) channels and/or digital input/output (DIO) channels that are synchronously
updated by a clock source defined by the application.

The daqDacWaveDisarm function will disable the waveform/pattern output on the specified device and
terminate any output buffer transfers that are currently active (see daqDacTransferStop for more details
on output buffer transfer termination). Waveform/pattern output will be terminated immediately, regardless of
the current state of the waveform/pattern output or the state of the digital-to-analog converter (DAC) or digital
input/output (DIO) channels from which the waveform/pattern output is being generated.
