Question

(IN C)

Note: I just need an example of this, use whatever extra variables you need. the queue is a First come First Serve style queue.

* Check if there are any processes still in the queues.
* Return TRUE if there is. Otherwise false.
*/
bool isScheduleUnfinished( schedule *ps ) {
/* check if there are any process still in a queue. Return TRUE if there is. */

return false; /* Replace with your return value */
}

Answer 1

As you have mentioned you need an example of this, so before that we will write the complete function isScheduleUnfinished() and accorrding to it, we will state one example.

So, the complete isScheduleUnfinished() function is written as follows:

bool isScheduleUnfinished( schedule *ps ) {
bool isAvailable = false;

/* Below we check if there is any address assigned to ps, if it is not NULL, then atleast one process is scheduled */

if ( ps != NULL )

isAvailable = true;

return isAvailable;
}

Now, let us take one example.

Example 1:

ps = P0

ps -> P1 -> P2 -> P3 ->NULL

Here, there are 4 processes, P0, P1, P2, P3.

Since ps != NULL is true, hence, isAvailable is updated to true.

Example 2:

ps = NULL

Here, there are 0 processes.

Since ps != NULL is false, hence, isAvailable remains false.
