to Comedi: Linux Control and Measurement Device Interface

I have a pci board Adlink 7433

64 digital inputs

it works well with comedi driver and linux

It has two subdevices 0 and 1, and each subdevice has 32 channel starting from 0 to 31

Is there a comedi function to read all channels status?

comedi_data_read seems to read one channel at time, so I need to do a for cycle to read all pins
