NAME

       comedi_set_filter - select a filter for a subdevice

SYNOPSIS

       #include <comedilib.h>

       int comedi_set_filter(comedi_t * device, unsigned int subdevice, unsigned int channel,
                             unsigned int filter);

STATUS

       alpha

DESCRIPTION

       This function selects a filter for a subdevice. For instance, a digital input subdevice
       may provide deglitching filters with varying cutoff frequencies. The filters are used to
       prevent high-frequency noise from causing unwanted transitions on the digital inputs. This
       function can tell the hardware which deglitching filter to use, or to use none at all.

       The filter parameter selects which of the subdevice's filters to use, and is
       driver-dependant.

       This function is only useable on subdevices that provide support for the
       INSN_CONFIG_FILTER configuration instruction.

RETURN VALUE

       0 on success, -1 on error.
