The SerCxGetReadIntervalTimeout method returns the interval time-out value for a read (receive) operation.
Syntax
ULONG SerCxGetReadIntervalTimeout(
[in] WDFDEVICE Device
);
Parameters
[in] Device
A WDFDEVICE handle to the framework device object that represents the serial controller.
Return value
SerCxGetReadIntervalTimeout returns the read-interval time-out value in milliseconds. A value of zero indicates that read-interval time-outs are not used.
Remarks
The read-interval time-out value is the maximum amount of time, in milliseconds, that is allowed between two consecutive bytes in a read operation. A read operation that exceeds this maximum times out. For more information about time-out values, see SERIAL_TIMEOUTS.
A read (IRP_MJ_READ) request successfully completes when the requested read operation times out. The request returns the STATUS_TIMEOUT status code to indicate that the operation timed out.
