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.
Name
ieee1284_set_timeout - modify inactivity timeout
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.
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.
