niHSDIO Allocate Named Waveform
Reserves waveform space in onboard memory and associates a waveform name with it. Individual waveforms are stored contiguously in onboard memory.
The name given to the waveform is the same name used in the niHSDIO Write Named Waveform VI to populate the waveform with data, as well as the waveform name referenced in scripts.
If space is unavailable to accommodate a waveform of size size in samples, an error is returned and no memory space is allocated.
This VI does not change any data on the device itself, but rather adds the named reference in software. Use the niHSDIO Write Named Waveform VI to fill the onboard memory with waveform data to be generated.

instrument handle identifies your instrument session. instrument handle was obtained from the niHSDIO Init Acquisition Session VI or the niHSDIO Init Generation Session VI. | ||||||||
 |
waveform name represents the name to associate with the allocated waveform memory.
You should name waveforms using this VI under either of the following conditions:
|
||||||||
 |
size in samples specifies the number of samples to
allocate for the named waveform.
The number of bits in the allocated samples differs depending on the device you are using.
|
||||||||
 |
error in describes error conditions that occur before this VI or function runs.
| ||||||||
 |
instrument handle out passes a reference to your instrument session to the next VI. instrument handle was obtained from the niHSDIO Init Acquisition Session VI or the niHSDIO Init Generation Session VI. | ||||||||
 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
