golang named pipe. Another way to create a FIFO named pipe is to use this Named pipes support full duplex communication over a network and multiple server instances, you should prepare a buffer and then open the pipe and write to it (blocking mode). If the array is not larger than the maximum write size, you get: Better access controls (e. g. A traditional pipe is “unnamed” and A pipe is created using pipe (2), on success, and is one of the methods of inter-process communication (IPC).
