Write 2 programs that will communicate via shared memory and semaphores. Data will be exchanged via memory and semaphores will be used to synchronise and notify each process when operations such as memory loaded and memory read have been performed.

Hiii

I tried to write a small program in C.

#include<stdio.h>
#include<math.h>
int main()
{
printf("\n\n the 4^3 = %d",pow(4,3));
return 0;
}

And I compile like $gcc -lmath pgm1.c

but it doesn't work..What may be the reason.

Thanking you

Used cluster number of a hard disk partition come continuously...Is

Hii

I duplicated my NTFS partition.And in that partition some of the folders is not opening " .While opening the message comes "File or directory is corrupted and and unreadable".

Here in my application I use the control code"FSCTL_GET_VOLUME_BITMAP " to get the cluster usage(cluster is used or free) details.And I'm copying only used clusters from my source partition to destination partition.

And I think the files in the duplicated partition not getting the link among them correctly.
Because I am copying the used clusters only so the free space in the source partition is discarded.So I've re-initialize the link...?

Can I do that one...???
How to do that....?
Where I've to make change...? In the volume boot record of that duplicated volume..?

Thanking you
