documentation about COMEDI buffer

	Hi all!

	 

	I am trying to write a COMEDI driver for a PCI data acquisition
board. One of the functionalities that I have to implement is the
asynchronous acquisition of analogue signals by using DMA.

	Does somebody have a little description of (or could explain to
me...) the correct use of the COMEDI buffer to transfer the data from the
DMA buffer? I have looked in other drivers. Some manipulate directly the
fields of the comedi_async_struct, other use functions as comedi_buf_put()
or cfc_write_array_to_buffer() and other use both. This all is very confuse
for me... I would very appreciate your help.

	Thanks all.

	 

	Eric
