Proactor and reactor in Aces Ace_select_reactor is the default reactor implementation that is used by all platforms except Windows and will eventually wait with the Select () system function on those systems. Ace_wfmo_reactor on Windows is the default reactor implementation. The implementation does not use the Select () multiplexer, but instead uses the WaitForMultipleObjects (). When using Ace_wfmo_reactor, some tradeoffs are needed: Ace_wfmo_reac

. Turn off standard input. The process is no longer able to receive any input, even if it is running in the foreground. REDIRECT standard output and standard error to file nohup.out . In other words, the nohup command actually separates the child process from the session it is in.Note that the nohup command does not automatically turn the process into a "background task", so you must add a symbol.Seven, screen command and Tmux commandAnother idea is to use the terminal

requires three main components: the combination logic that computes the function that operates on the bit, the memory element that stores the bits, and the clock signal that controls the update of the memory element. And, or, not three kinds of logic gates can be implemented with a gate (with a non-gate, or not gate). Multiplexer. The multiplexer selects one from a different set of data signals based o

With the advent of IO multiplexing technology, there are many event processing modes. The synchronous I/O model is typically implemented by the reactor pattern, while the asynchronous I/O model is implemented by the proactor pattern. Reactor mode: As shown above, the reactor mode is also called a reactor or reactor, the processor that implements the registration descriptor (HANDLE) and the event (EventHandler), and when an event occurs, the event Reator Demultiplexer) responds by i

compatible.SATA II is developed on the basis of SATA, and its main feature is that the external transfer rate is further increased from 1.5G SATA to 3G, including NCQ (Native command Queuing, native commands queue), Port multiplexer (ports Multiplier), staggered start (staggered spin-up) and a series of technical features. Pure external transfer rate of 3Gbps is not true SATA II.The key technology of SATA II is the external transfer rate and NCQ tech

The AHB system consists of a master module, a module and an infrastructure (Infrastructure) 3 part, the transmission of the entire AHB bus is issued by the main module, from the module responsible for response. The infrastructure consists of an arbiter (arbiter), a master module, a multiplexer from a module, a multiplexer from a module to a mas

The fact is that the PES package is decomposed into a smaller PS package .at the time of decoding, the multiplexer decomposes PS into a PES package, unpacking and then splitting the PES pa

The answer is very good. Sockets and Socketchannel are two sets of APIs, for network TCP communication is not concerned about what API you use to achieve communication. So the answer is yes. Socketchannel can be set to non-blocking, so in some cases the performance is better and the thread will not be suspended. Socketchannel can also register selector and events of interest. Selector Multiplexer There is not much to introduce.The flow of data in the
