comedi_cancel ā€” stop streaming input/output in progress


#include <comedilib.h>

int comedi_cancel (comedi_t * device, unsigned int subdevice);


The function comedi_cancel() can be used to stop a Comedi command previously started by comedi_command() that is still in progress on the subdevice indicated by the parameters device and subdevice. This may not return the subdevice to a ready state, since there may be samples in the buffer that need to be read.

If sucessful, 0 is returned, otherwise -1.
