[Libburn] Progress details

[Tiago Cogumbreiro]

Hi again,
I've been playing around with your burniso.c example and i was wondering
how to work with progress, i was trying to use it like this:

	struct libburn_progress prog;
	int ret = libburn_drive_get_busy(drive, &prog);
	if(ret) {
		printf("Session: %d/%d ", prog.session, prog.sessions);
		printf("Track: %d/%d " , prog.track, prog.tracks);
		printf("Index: %d/%d " , prog.index, prog.indices);
		printf("Abs Sectors: %d/%d ", prog.abs_sector, prog.abs_sectors);
		printf("Rel Sectors: %d/%d ", prog.rel_sector, prog.rel_sectors);
	}

This is the output i get:
S: -1073743820/1078199456 T: 1078312456/1073836040 I: 0/-1073743864 AS:
1078312456/134532312 RS: 0/-1073743848
S: -1073743820/1078199456 T: 1078312456/1073836040 I: 0/-1073743864 AS:
1078312456/134532312 RS: 0/-1073743848
S: -1073743820/1078199456 T: 1078312456/1073836040 I: 0/-1073743864 AS:
1078312456/134532312 RS: 0/-1073743848
(...)

My question is the following, is the progress implemented or am i using
it wrong? If it is which operations supported and which don't?

Thank you.
