.SH "DESCRIPTION"

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

.PP
The \fIport\fR must be claimed\&.

.PP
The \fItimeout\fR parameter may be \fBNULL\fR, in which case the old value is left unchanged\&.

.SH "RETURN VALUE"

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

.SH "NOTES"

.PP
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\&.

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