GNU/Linux standard I/O functions (stdio et. al) provide an efficient way to dealing with data streams. By default, they provide a line-buffered behavior. Most of the time, this is not important, but it may be sometime needed to have no bufferring at all. This can be useful when immediate handling of keypresses is needed.
A buffer is used to keep from doing expensive operations repeatedly - for instance, when writing individual characters to an output channel - such as (H,E,L,L,O, ,W,O,R,L,D) - without a buffer the system would be forced to do the whole output(H)-> Jul 19, 2020 · I/O streams are denoted by objects of type FILE that can only be accessed and manipulated through pointers of type FILE *. Each stream is associated with an external physical device (file, standard input stream, printer, serial port, etc).

Sep 19, 2017 · The text I/O layer will still be line-buffered if writing to the console, or block-buffered if redirected to a non-interactive file. See also PYTHONUNBUFFERED.-v¶ Print a message each time a module is initialized, showing the place (filename or built-in module) from which it is loaded.
stderr is line-buffered by default. If you are using a memory file, z/OS XL C/C++ does not use any buffering. For terminals, because I/O is always unblocked, line buffering is equivalent to full buffering. I learned that by default I/O in programs is buffered, i.e they are served from a temporary storage to the requesting program. I understand that buffering improves IO performance (maybe by reducing system calls). I have seen examples of disabling buffering, like setvbuf in C. What is the difference between the two modes and when should one be Line buffering works on lines instead of disk sectors. Line buffered I/O reads through the next newline, then passes on the buffer. By running tail -f on a file which is slowly being written by another program, you can see block buffering in action. The output pauses in the middle of a line, then all of a sudden, after a longish wait, you get
