NAME

       comedi_dio_write - write single bit to digital channel

SYNOPSIS

       #include <comedilib.h>

       int comedi_dio_write(comedi_t * device, unsigned int subdevice, unsigned int channel, unsigned int bit);

DESCRIPTION

       The function writes the value bit to the channel channel belonging to the subdevice subdevice of device
       device. This function is equivalent to:

           comedi_data_write(device, subdevice, channel, 0, 0, bit);

       This function does not require a digital subdevice or a subdevice with a maximum data value of 1 to work
       properly.

       If you wish to write multiple digital channels at once, it is more efficient to use comedi_dio_bitfield2
       than to call this function multiple times.

RETURN VALUE

       Return values and errors are the same as comedi_data_write.
