IOCTL_FARC_GET_READ_TIMEOUT

Purpose: retrieve currently set timeout value in ms units

Parameter:
IN:   -
OUT:  ULONG ulTimeoutValue

Possible errors (see also Error codes):
E_FARC_INVALID_HANDLE
E_FARC_BUFFER_TOO_SMALL

Comment:
Retrieves the previously set timeout value for ReadFile operations in the driver.

Note: A return value of '0' means, that the driver waits infinitely for the receipt of an ARCNET data packet when performing a ReadFile operation (this is the default state).

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;
 ULONG ulTimeout;

 overlapped.Offset = 0;
 overlapped.OffsetHigh = 0;
 overlapped.hEvent = CreateEvent(NULL,TRUE,FALSE,NULL);

...

  ret = DeviceIoControl(drvhandle,
     IOCTL_FARC_GET_READ_TIMEOUT,
     NULL, 0,
     &ulTimeout, sizeof(ulTimeout),
     &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
   {
      // other error occured, perhaps wrong handle
   }
}
printf ("Currently used timeout value: %lu", ulTimeout) ;
