NAME
       comedi_data_write - write single sample to channel


SYNOPSIS
       #include <comedilib.h>

       int comedi_data_write(comedi_t * device, unsigned int subdevice, unsigned int channel,
                             unsigned int range, unsigned int aref, lsampl_t data);


DESCRIPTION
       Writes a single sample on the channel that is specified by the Comedi device device, the subdevice
       subdevice, and the channel channel. If appropriate, the device is configured to use range specification
       range and analog reference type aref. Analog reference types that are not supported by the device are
       silently ignored.

       The function comedi_data_write writes the data value specified by the parameter data to the specified
       channel.


RETURN VALUE
       On success, comedi_data_write returns 1 (the number of samples written). If there is an error, -1 is
       returned.
