Here is the caller graph for this function:

getFullBuffer()

Eigen::Array<unsigned short int, Eigen::Dynamic, Eigen::Dynamic>* IIOThreaded::getFullBuffer ( void  )

inline

Get the full buffer.

Returns

The buffer which was last filled.

Definition at line 130 of file IIOThreaded.H.

Here is the caller graph for this function:

resizeBuffers()

int IIOThreaded::resizeBuffers ( int  N, int  ch  )

inlineprivate

Resize the internal buffers for reading. The end result will be buffers which capture N samples per channel, where the total number of channels is the number requested + the remainder non-requested channels on the last device. i.e. the total number of channels will be ceil(ch / number of channels per device) * number of channels per device. For example, if ch=3 but there are 2 channels per device, we will get ceil(3/2)*2 = 4.

Parameters

N	the number of samples to read.
ch	the number of channels to read.

Returns

NO_ERROR or the suitable error. The arrays are returned correctly sized for reading N samples.

Here is the caller graph for this function:

threadMain()

void* IIOThreaded::threadMain ( void  )

inlineprivatevirtual

All reading is done in a threaded environment. This ensures that you can process data whilst new data is being read in.

Implements ThreadedMethod.
