Thanks! Completely overlooked that they talked about ‘description’, not ‘descriptor’ in several places. It would have helped me if they pointed out that difference in a clearer way. The Linux man page says ‘Locks created by flock() are associated with an open file description (see open(2))’, and that says: “The term open file description is the one used by POSIX to refer to the entries in the system-wide table of open files. In other contexts, this object is variously also called an "open file object", a "file handle", an "open file table entry", or—in kernel-developer parlance—a struct file.”
