Quote:

The this pointer is a hidden pointer inside every class's non-static function which points to the class's particular object through which the concerned function is called.

Example:

Code:

class A
{
    private:
        int rollNumber;

    public:
	A (int rollNum)
	{
	    rollNumber = rollNum;
	}

	void setRollNumber (int rollNum)
	{
	    rollNumber = rollNum;
	}
};

My birthday presents

So, I turned 29 on 18th Feb 2012. Thought of presenting
myself with the toys I was longing for quite a while.
Nikon D3100 (body only).

Nikon AF-S NIKKOR 50mm f/1.8G.

Bajaj Oven Toaster Griller (3 in 1) 28 ltrs.

Owned Canon PowerShot SX210 IS for about two years.
That camera produces horrible outputs in low light.
No wide apertures. Horrible noise at ISO 200.
I was discouraged. Discouraged to the level that I had
totally abandoned...

Why and how to use Mutex locks - Pthreads

Posted 02-27-2012 at 11:06 AM by Anisha Kaul

Problem:
Underlying operating system may schedule the threads on the basis of some algorithm which works on time limit (threads may be allowed to run only for certain durations of time, thus preventing the other threads from starvation), priority (higher priority threads may interrupt the lower priority threads during their execution), or some other factor.

These factors may cause a thread to sleep before it completes its task fully. Another thread may get scheduled meanwhile...
