You don't get an argument from me on this. :-) I actually used this to verify my program. It is short, but not as much educational as writing a C- program.
short x; ssize_t size = read( fd, &x, 4 );
Shorts aren't 4 bytes. Perhaps you should change the '4' to:
sizeof(short) or sizeof(x)
It does not chane the result. I used the 'short' to get away from a printout with four bytes (high order first, followed by low order) which was confusing and not what was asked.
or even better, use mmap(2).
I will experiment with this as a next step in my education.
Or even way better, read a book:
Better, but a lot more cumbersome. In addition, it is very hard to find what one needs in specific cases. Just read some of the responses to my original question and you will see that my problem was not of a nature to bring forward answers from people that have read a lot of the pertinent books.

It'll be much less painful.
