Dave,

It seems to me comedi_perror() usually doesn't work.  For example, if you try 
to run the outp demo on a subdevice that doesn't support output, the 
comedi_perror() call will report success instead of the EINVAL message.  From 
briefly looking at the error code, it seems like libc_error() (or some 
function that sets __comedi_errno according to the value of errno) needs to 
be called after every ioctl that returns an error.  So, we I guess we would 
want to start using a wrapper function named something like comedi_ioctl() 
that does this?
