without checking the actual code: the shmid can be any 32bit integer, e.g. 156823457 since Pd uses 32bit single precision floats, the given id might not be representable by a Pd-atom. the hash i'm using is only 16bit, and thus always representable by a Pd-atom. ftgmasdr IOhannes -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAlErh9UACgkQkX2Xpv6ydvQD5ACdGKqjFP2lJolNwudvE98KbrVY ZZsAoO2z1R2MnSEhKg4txvkqUrpIKDsz =f6Zo -----END PGP SIGNATURE----- _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
