Try deleting junkfile before running the program, or open with O_TRUNC
instead of O_CREAT.

Your original program will produce a 7-byte file.  With O_BINARY, the
program writes only 5 bytes but if the file already exists it won't be
truncated.

"info libc a open" lists the options and their meanings.
