Questions tagged [asyncsocket]

Asynchronous sockets allow for multiple simultaneous non-blocking socket connections.

Asynchronous sockets allow for multiple socket connections within a single thread. While more complicated than synchronous sockets, asyncsockets allow for more efficient use of cpu scheduling. These connections are non-blocking, which allows the main program thread to continue running, while a socket thread manages network traffic.

socket.connect() blocks other threads?

If I issue multiple socket.connect() in different threads - would a single socket.connect() make the current thread to wait for an ACK response, or meanwhile another thread would be able to issue a socket.connect()?
