There was no specific error as such. I was doing this thing on a interview portal and their after checking with reference , it is compiling ok but giving some sanity error. that i am trying to figure out. what could be missing here.

Hi, Thanks for your response. Actually I have included header file and also provided lib reference as mentioned in post in TARGETLIBS section of sources file, but still getting issue. Let me explain with an example:
Suppose i have function in ProjectA.dll as projectAfun();
Now this function is used in ProjectB.lib. When I build ProjectB, this is compiling properly. Now When I use static lib ProjectB.lib in my ProjectC and also include header file of ProjectA and give refernce of ProjectA.lib in ProjectC, I am still getting following error -
ProjectB.lib(ProjectB.obj) : error LNK2001: unresolved external symbol projectAfun

Regards

As you said , It does use physical memory, but only a relative small window compared to the actual size. But if we want we can map whole file to physical memory if that amount of memory is available. Am I correct?
One more thing why the referred article is saying that File mapping object does not cost us any system resources as physical memory is also a system resource. So what does that mean?

yes please. have a close look at it. as it will solve my very important problem. Thanks

The problem persist, please check it on c compiler

Ok I will once again check it. and note that the code is in C not c++.

I have also tried the above code but it is also not working

I got your point that value of any variable as a constant value under any circumstances. But my problem is that we accessing the address in both cases as shown below:
1. &(pRahulTvar->rahul[0]),//this is giving error: error C2099: initializer is not a constant
2. &(RahulTvar.rahul[0])// it is working properly
And 2nd is working properly, only 1 is giving error and why, I am still not clear. Could u please look into this and elaborate ur answer in reference with the above two lines.
Thanks in advance.

now have a look at question and suggest me proper solution or workaround.
thanks in advance

@Stefan So you are saying that queue is just for specific purpose and it let people know about its behaviour that what it is intended for. That's all why queue is introduced. Am I correct..

It's disabled in Visual studio. How does it matter?

@OriginalGriff I have tested the same code as mentioned by you but it stops execution at "int k=9/i" showing unhandled exception while debugging.

@CPallini catch(...) is for catching any and all types of exceptions thrown from try block.
or it is only for C++ exception as u mentioned.

thanks for observing that

sry for misunderstanding.
Thanks for ur explanation.

Means u r saying that it will results in unexpected behaviour(unsafe) that is why compiler is giving error.
I don't know whether this explanation is right or not.
By the way I have some doubt that is why I have put this question. Sorry, It is not a matter of laughing. Ur knowledge is of no use unless u r able to make it clear to someone.
May be I am not able to get it properly.

I am Ok with ur explanation.
But my 2nd question is still remain unanswered i. why cant we put normal code outside the funtion.

Its Ok then.
Why the problem occured I m still not clear.

can u elaborate ur answer?

But if I want to use that global map in some other funtion then how can we access the map if we declare that in main function.
And why cant we write normal code outside a function.
