Type of Linux/Unix I/O

i have to make a presentation about Linux/Unix I/O: File I/O,Standard I/O, buffered/unbuffered I/O and formatted/unformatted I/O.

i'm not sure how to order these kinds of I/O to make sense.

here is my try:

  • file I/O
    • unbuffered I/O
    • buffered I/O
      • Standard I/O
      • formatted/unformatted I/O

is this correct ??

thx anyway

Solution

  • It looks like a good start. I would add the following topics:

    • asynchronous I/O: epoll, poll and select
    • scatter/gather operations: readv, writev
    • memory-mapped I/O: mmap
