> Description
</H2
><P
>The function comedi_fileno returns the integer descriptor for
the device dev. This descriptor can then be used as the
file descriptor parameter of read(), write(), etc.
This function is intended to mimic the standard C library
function fileno(). If dev is an invalid comedi_t
pointer, the function returns -1 and sets the appropriate
Comedilib error value.</P
