I am trying to implement a socket server by using epoll.
I have a server that receives a continuous stream of data. As opposed to reading multiple times from a socket, I would like to read the entire data in socket receive buffer with one system call to read().
Of course I can pass a large buffer and read() will try to fill it with all available data.
I have searched for a neat explanation of how to use sockets to receive and send files in linux, but i can't find a solution that even works a little bit.
I have a c++ server on linux, and a client which runs in java.
I need it to do the following:
Client needs to be able to send text-commands towards the server.
Client needs to be able to send/receive files towards the server.
Server gets the
I'm new to Java so I need help please. I'm writing an application that will onClick send a String to Server and Server needs to return an image using socket. So my client side is Android and server side is PC - java.
I think that my server side is ok (because he prints out all the system.out.print commands) but my client side is not good. Please tell my where is my mistake?
I have decided to use async io for my project and simply do a single threaded loop where I try to read some data each frame from each open socket. This worked quite well and overall I'm happy with it for now. The problem is weird problems I'm having with the async sockets.
I'm trying to create a client socket to send a http request to a server, but an error is occurring in the function connect, in turn primeir returned this error: "connect: Socket operating on non-socket 'and' connect: no such file or directory 'I did not find anything wrong in my code so I went looking two examples of client sockets, and they tanbem returned this error.
my code is this:

I would like to write a script that takes something like this:
Line 1
Line 2
Line 3
Line 4
[Blank line]
Line 6
Line 7
Line 8
Line 9
[Blank line]
etc....
And makes it to look like this:
Line 1|Line 2|Line 3|Line 4|[Blank line, if it's easier]
Line 6|Line 7|Line 8|Line 9|[Blank line, if it's easier]
etc.
I would think it would be fairly easy to use two loops, one for the the 5-li
Hi,
New year wishes to everyone!
I have to design a GUI for an embedded system application. I should be able to control the system via the GUI (start, stop and specify other parameters as needed) and also display the output from the system to an end user.
I have two file descriptors, one read file descriptor on pipe and another socket connection descriptor. Neither of them is non blocking. Both of them are added to epoll context with single EPOLLIN event. Lastly, i call epoll_wait with timeout = -1. Below is the sample code. I have
two questions :-
Do pipe and connection descriptors need to be non blocking. This is not edge triggered.
