Hi, Thanks for the reply.. In Linux, we were using these APIs for processing the data between user managed space and kernel space. Similar requirement has come up for Mac OS X. So User Application cannot use this APIs since it is not available in the man pages right? Which are the appropriate APIs that can be used for exchanging the ACL data between kernel and user space.

You mean will Apple republish the POSIX 1003.1e draft standard on which most ACL implementations are based, and which shows up as the first Google hit when searching for the phrase posix 1003.1e draft standard ACL Probably not; the published documentation in the draft standard is pretty sufficient. You should note that the format of the first argument to acl_copy_ext() and the only argument to acl_copy_int() is a contiguous, persistent data item, the format of which is unspecified. It is intentionally unspecified, since it contains data for which no reasonable APIs could be created, and maintain coherence between the data contained there and the active credential data associated with the POSIX credentials on a file system object to which an ACL has been attached, at the time of a file create or ownership modification request happens. Basically, you are intended to use read/modify/write semantics so as to not cause these values to become disjoint, so there really isn't any valid reason for the internals to be documented. I was actually unable to find actual usage of these functions not internal to ACL implementations themselves in a brief google search on the subject. -- Terry _______________________________________________ Do not post admin requests to the list.

The above APIs are not documented in the man pages of Mac OS X 10.4 but are available in its libc library. Will Apple document these APIs for other application to use or not? If these APIs are not available for other applications, what are the other appropriate APIs to replace them in Mac OSX.

None of the files contain anything interesting though, just the process that was running, its parent and how long it was hung for and other uninteresting data. No stacks or other useful information. My question is, is this normal? Under what circumstances are the .hang files populated with useful information?
