-/* Close standard output, exiting with status 'exit_failure' on failure.
- If a program writes *anything* to stdout, that program should close
- stdout and make sure that it succeeds before exiting. Otherwise,
- suppose that you go to the extreme of checking the return status
- of every function that does an explicit write to stdout. The last
- printf can succeed in writing to the internal stream buffer, and yet
- the fclose(stdout) could still fail (due e.g., to a disk full error)
- when it tries to write out that buffered data. Thus, you would be
- left with an incomplete output file and the offending program would
- exit successfully. Even calling fflush is not always sufficient,
- since some file systems (NFS and CODA) buffer written/flushed data
- until an actual close call.
-
- Besides, it's wasteful to check the return value from every call
- that writes to stdout -- just let the internal stream state record
- the failure. That's what the ferror test is checking below.
-
- It's important to detect such failures and exit nonzero because many
- tools (most notably 'make' and other build-management systems) depend
- on being able to detect failure in other tools via their exit status. */
