IOCTL_FARC_ENABLE_RECEIVE
Purpose: reenable the receiver of the ARCNET-controller (after IOCTL_FARC_DISABLE_RECEIVE)
Parameter:
IN: -
OUT: -
Comment:
This command must be preceeded by a IOCTL_FARC_DISABLE_RECEIVE.
Possible errors (see also Error codes):
E_FARC_INVALID_HANDLE
E_FARC_NOT_INITED
E_FARC_NO_DISABLE
E_FARC_PERFORMING_DISABLE
Example:
Note, that the following example is only a fragment. It is recommended,
that the driver is opened in asynchronous mode and a handle to the driver
is available.
OVERLAPPED overlapped;
DWORD read, err;
BOOL ret;
overlapped.Offset = 0;
overlapped.OffsetHigh = 0;
overlapped.hEvent = CreateEvent(NULL,
TRUE, FALSE, NULL);
...
ret = DeviceIoControl(drvhandle,
IOCTL_FARC_ENABLE_RECEIVE,
NULL, 0,
NULL, 0,
&read,
&overlapped);
if (!ret)
{
err = GetLastError();
if (err == E_FARC_PENDING)
{
ret
= GetOverlappedResult(drvhandle, &overlapped, &read, TRUE);
if
(!ret)
{
err = GetLastError();
// do errorhandling here
}
else
{
// Receiver now disabled
}
}
else
{
//
other error occured, perhaps wrong handle
}
}
