Rather than scatter fragile magic numbers, like 10, throughout the
code, if you're hell-bent on checking for printf errors you could
write a little wrapper function that hid the magic number and bundled
up the errno stuff.
But what would you expect printf error checking to tell a user?
Perhaps that he or she ran out of disk space, but that's going to be
painfully obvious anyway in almost every case.
