I have a client / server application where clients send messages to the server. Due to a legacy library that I use, my server cannot read immediately but must wait for a condition to come true until it reads the messages. How much data can a socket store? Is there a fixed buffer size/limit?
Thanks.
It depends on the size of the socket receive buffer, whose default value varies among operating systems. You can control it from your application via
setsockopt()and the SO_RCVBUFSIZE option.
