A non-blocking socket returns whatever is in the receive buffer and immediately continues. If not written correctly, programs using non-blocking sockets are particularly susceptible to race conditions due to variances in network link speed. [citation needed] A socket is typically set to blocking or non-blocking mode using the functions fcntl ...
Non-blocking algorithms generally involve a series of read, read-modify-write, and write instructions in a carefully designed order. Optimizing compilers can aggressively re-arrange operations. Even when they don't, many modern CPUs often re-arrange such operations (they have a "weak consistency model "), unless a memory barrier is used to tell ...
A network socket is a software structure within a network node of a computer network that serves as an endpoint for sending and receiving data across the network. The structure and properties of a socket are defined by an application programming interface (API) for the networking architecture.

After instantiating a new socket, the server binds the socket to an address. For a Unix domain socket, the address is a /path/filename.. Because the socket address may be either a /path/filename or an IP_address:Port_number, the socket application programming interface requires the address to first be set into a structure.
Racket's system interface includes asynchronous non-blocking I/O, green threads, synchronization channels, semaphores, sub-processes, and Transmission Control Protocol (TCP) sockets. The following program starts an "echo server" on port 12345.

In computing, a process that is blocked is waiting for some event, such as a resource becoming available or the completion of an I/O operation. [1] Once the event occurs for which the process is waiting ("is blocked on"), the process is advanced from blocked state to an imminent one, such as runnable.
