Tutorial for file binary in-out & buffers

[tonnot]

It is very difficult to find help about this.
I want to do i-o operations using buffers.
I want to read and write, strings, numbers of any kind, buffers , arrays, etc.
Any help ? I dont know how to continue.
Thanks

Buffer is just a block of memory. If you know where things are in it and where you want them to be, memcpy will solve most of your problems.
