Hi,

I would like to know how to read multiple files using fopen and send it to the server and how should the server receive all the files without data loss using tcp/ip protocol?

You will know it by implementing it all. You have to develop both client and sever parts. Any specific concerns?
And note, your question in the title makes no sense. fopen has nothing to do with "multiple" (it opens exactly one file) or "select" (what is that?)...

Anything you have tried so far?

@ Giri. I am able to read a single text file using fopen and send it to the server. Now i need to try with multiple files.

What is the problem? You just need to read each file in turn and send it to the server, until all files are complete.

@ richard. How can i read multiple files at concurrent time and send it to server in tcp/ip?

You would need to use multiple threads. But you would not necessarily get better performance that way.

@Richard. Can i achieve it through command line arguments int main(int argc, char argv[]) or by using multiple threads as per you said.

The two things are totally different, so I do not understand what you are asking. The arguments to a program just allow it to be fed some parameters on start up. Running multiple threads allows parallel processing within the application.

The easiest way would be like that pseudocode

C++

while( isFileTransferToServerPending() )
{
   SendNextFileToServer();
}

It is also the normal solution because file transfer will be the bottleneck, so multiple file transfer wont speed up your solution.

You can think about complex scenarios, as implementing some client/server logic in which you get a identifier from the server which is identifying the file and the client is packing multiple file data with that identifier and packet stamp to send it to the server.
