help: problem with sockets write/read
I am trying to make a server and client, the client will choose between some options and the server will react accordingly.

After a some reads and writes that work the server needs to read from client an INT i use this:

Code:
read(newSd,&k,sizeof(int));

But even if all the other times there was no problem
this time the server does not seem to block on read OR it reads something but without the client sending.I also wrote multiple reads in server after this one and no writes in client, still the server passed through them to the next lines of code.

What could cause this?

If it reads without the client sending, then there was data there waiting to be read which you didn't read before. You couldn't have been reading all the data the client sent.

Also, you should use send/recv for sockets, not read/write, though that wouldn't cause this problem.
