11       int comedi_sv_init(comedi_sv_t * sv, comedi_t * device,
12                          unsigned int subdevice, unsigned int channel);

DESCRIPTION

18       The function comedi_sv_init initializes the slow varying Comedi
19       structure pointed to by sv to use the device device, the analog input
20       subdevice subdevice, and the channel channel. The slow varying Comedi
21       structure is used by comedi_sv_measure to accurately measure an analog
22       input by averaging over many samples. The default number of samples is
23       100.

RETURN VALUE
