comedi_get_cmd_generic_timed(...) behavior

comedi_get_cmd_generic_timed(...) has some behavior
that is confusing to me and seems to be contrary to
the documentation.

According to the documentation "... The command structure pointed 
to by the parameter command is modified to be a valid command ..."
But what it seems to do is allocate a new comedi_cmd structure,
allocate memory for one channel in command->chanlist, and 
set the pointer command to point to this structure.
Is this right?

The reason I am asking about this is because I am writing 
a program where I want to be able to change the 
sample rate.  It looks like one cannot apply 
comedi_get_cmd_generic_timed() to an already existing
comedi_cmd structure without losing the 
information already in it.  Is there another way
to update the sample rate?

If someone could explain, I would appreciate it.
