Is one of these your starting point? What errors are you seeing? http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libc/port/gen/readdir.c http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libbc/libc/gen/common/readdir.c The libbc version hasn't changed since the code became public. You can get to an older libc variant of it by clicking on the history link or using the appropriate hg command to get a specific changeset. -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
