-/* Why do we care about stdout you may ask? Here's why, from Jim
- Meyering in the lib/closeout.c file. */
-
-/* If a program writes *anything* to stdout, that program should close
- stdout and make sure that the close succeeds. 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.
-
- 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. */
