14 The function comedi_fileno returns the integer descriptor for the
15 device dev. This descriptor can then be used as the file descriptor
16 parameter of read(), write(), etc. This function is intended to mimic
17 the standard C library function fileno(). If dev is an invalid
18 comedi_t pointer, the function returns -1 and sets the appropriate
19 Comedilib error value.
