RTFM for fopen, chmod, and umask.

"Access" controls who can do what operations on the file.

"Mode" tells the open command what your program wants to do right now (and
the "access" controls if you will be allowed to do it).

'w+' does not create a file with write _access_, it opens a file _handle_
in read/write _mode_.

It is perfectly possible to open (and thereby create) a new file using a
file handle in write _mode_, but for the file thus created to have read
only access permissions.
