Contents
Parameters
HANDLE StreamH
- The stream that is to be read
LONG TimeUS
- The time offset to extract the history from, in microseconds
ULONG TimeStep
- The step in microseconds between each sample extracted
ULONG Samples
- The number of samples to extract - this will expand the array

- The buffer to read the sample data into
Return value
Returns the block of the output stream with each input sample operated on, returns number of samples read
Detailed description
No additional information
Examples
Calling in a calculation
- Declare a variable 'result' of type ULONG
- Add to a calculation icon:
result = ::Scope.GetOutputBlock(streamh, timeus, timestep, samples, _arraybuffer)
