SYNOPSIS

       #include <ieee1284.h>


       struct timeval *ieee1284_set_timeout (struct parport *port,
                                              struct timeval *timeout);

DESCRIPTION

       This function sets a new value for the  inactivity  timeout  (used  for
       block transfer functions), and returns the old value.


       The port must be claimed.


       The  timeout parameter may be NULL, in which case the old value is left
       unchanged.

RETURN VALUE

       This function returns a pointer to a struct  timeval  representing  the
       old  value. This uses the same storage as the port structure, and so is
       not valid after closing the port.

NOTES

       Note that this is an inactivity time-out,  not  an  absolute  time-out.
       During a data transfer, if the peripheral is inactive for the length of
       time specified then the host gives up.


       It is also advisory; no guarantee is made that the transfer  will  ever
       complete.
