Recall the return value conventions for fputc (of type int)
``If there are no errors, the same character that has been written is
returned. If an error occurs, EOF is returned and the error indicator
is set''
where the EOF macro expands to a negative int, and flint_fprintf (of type int)
``On success, the total number of characters written is returned.
On failure, a negative number is returned.''
