What would be wrong with using a letter, a colon, and a number to describe the field? So, instead of 2/10/10/10 you'd have A:2/R:10/G:10/B:10. Or A:8/I:8 for aIndex 88. I'm not familiar with how sysfs attributes work, so this may be pure nonsense. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFC9ncYX1gOwKyEAw8RAnjwAJ4mVXa5RGo/1yja036IdUi8U+2wyACfe8gg mloAzlOC33YqPCP6zM6BHKM= =Qr6o -----END PGP SIGNATURE----- ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf -- _______________________________________________ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
