Now that I think about it, my version leaks a file descriptor when
write_to(file) did not succeed.
If that is bad, Ben's version is better (after fixing the two typos:
the returnvalue of fclose() and the misspelling of write_it/wrote_it)
static bool use_and_close_valid_file(FILE *file)
{
bool const wrote_it = write_to(file);
return 0 == fclose(file) && wrote_it;
}
