Do I need locks to write into socket using the same application twice and simultaneously?

hop of those help? No, you should not use locks for writing in this case. Think about it: how would two programs written by two different companies work on the same machine if they needed to take locks before writing to independent sockets?
Even writing to two separate sockets in the same program does not require locking.

should help you out You can use two threads. One for reading and one for writing. This way the write thread can write whenever it pleases (don't need to stop the read).
Another way to do it is to use setSoTimeout(timeoutMs) on the socket before calling read. This will cause it to throw a SocketTimeoutException if it takes longer than timeoutMs milliseconds to read, allowing you to then write as you please.

will help you I am implementing a simple server, that accepts a single connection and then uses that socket to simultaneously read and write messages from the read and write threads. What is the safe and easy way to simultaneously read and write from the same socket descriptor in c/c++ on linux? I dont need to worry about multiple threads read and writing from the same socket as there will be a single dedicated read and single dedicated write thread writing to the socket. ,
In the above scenario, is any kind of locking required?

This might help you First off- never use execute.get(). If you think you need to use it, you're architected wrong- it breaks the entire point of using a thread to have the calling thread wait for a result. If you just call execute, you'll run on another thread and work fine. If you need more than 1 thread running truly simultaneously, use executeOnExecutor() to override the 4.0 shared thread pool mechanism of AsyncTask.
Or better yet- don't use AsyncTask for this. You have something you want to run forever, waiting for input from a remote connection. This is a better fit for a Thread than an AsyncTask. I'd go with a thread and have the while loop built into the thread, and have the thread terminate only when the connection is closed.

should help you out It's probably because readFromSocket(socket) is synchronous, then readFromSocket(socket).forEach will block and the codes after it won't be able to run. You can add a log after readFromSocket(socket).forEach to check it.
To resolve this issue, you can use readFromSocket(socket).subscribeOn(Schedulers.io()) to run the read actions in the IO thread pools.

wish of those help For Unix kernel two threads one reading and other writing to a file (socket) is same as two processes doing the same. As the kernel is capable of Multiplexing the IO you don't need to worry.
