sending extra arguments

hi all.

i am writing comedi driver for isa card with analog and digital output.
analog i/o in this case is realized for interaction with analog
modules 73L-xxx (where x - some number or some letter). but, for
example, for analog reading, i need to send to reading function
73L module offset(there are few offset values provided by different each
module). so i need to send some extra arguments to
comedi_data_read/comedi_data_write
functions.  how can i do it without adding some special function in comedi?

10x for help.
