site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com User-agent: Thunderbird 2.0.0.12 (Macintosh/20080213) Is there a way to convert the node names to full paths, or even CFURLs? I would like to avoid using the I/O Kit if possible. Thanks, Mike _______________________________________________ Do not post admin requests to the list. They will be ignored. Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… I need to get the full paths to all the *mounted* volumes in the /Volumes dir. I've seen Quinn's VolumeToBSDNode sample. But I would like to convert BSD node names to fullpaths for each volume, and possibly to FSRefs after that for use with the File Manager. Or is there any easy way to index over the volumes to get their full paths the way GetCatalogInfo used to do it in Classic Mac OS? This email sent to site_archiver(a)lists.apple.com

Is it the correct approach or there is any other way to get the same ? OS version is 10.4.7 Thanks in advance!

Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… I was wondering if an equivalent of failmalloc (http://www.nongnu.org/ failmalloc/) exists for OSX ? failmalloc is dependent on glibc memory allocation scheme, so does not work on OSX. If not, I will write one such library. I am wondering if it is OK to introspect libgmalloc for finding all the malloc related functions that are rerouted for testing ? I need to override less functions (only the one that allocates memory and could fail) but I think libgmalloc have an exhaustive list of entry points.
