    Thanks for your assessment of my code.  I'm just
the sloppiest guy going.


Well, that's what *I* do <grin>.

I assume that if fprintf returns a negative value the disk
is full.

It is the only portable thing I can do without tying the
code to some specific printf implementation.

It would be much better if I could portable write

err = fprintf(...);
if (err == EOF) {
	// no space. Erase temporary files
}

This could be encapsulated in a
int MyFprintf(FILE *f,char *fmt,...)
{
	int err = fprintf(... /*call ellided*/);
	switch (err) {
		case EOF:
			// No space. Erase temp files
			break;
		default:
			// Other errors
	}
	return err;
}
.
