niHWS_WriteAnalogF64
C Function Prototype
tHWS_Status niHWS_WriteAnalogF64 (tHWS_WfmRef wfmReference, long numSamples, const double* wfmData);
Purpose
Writes double-precision floating-point analog waveform data into the waveform beginning at the current read/write position.
A write moves the read/write position so that it points to the next sample to be written. Repeated writes to the same waveform concatenate data to that waveform.
Parameters
| Name | Type | Description |
|---|---|---|
| wfmReference | tHWS_WfmRef | References the waveform. Waveforms are identified by reference for purposes of setting and getting waveform attributes and reading and writing data. |
| numSamples | long | The number of samples in wfmData to write to the file. |
| wfmData | const double* | The array containing the data for the waveform. It is assumed that this array contains at least the amount of data indicated by the value assigned to numSamples. |
