• Patch to update the mkdir (2) manpage (/usr/share/man/man2.Z/mkdir.2) to
include changes for the ENAMETOOLONG return value returned by the mkdir (2)
system call.
Impact
• The LibcExt product will aid in migration from Tru64 UNIX and Sun Microsystems
Solaris.
•Shared mmap() of /dev/zero will succeed and behave as a shared MAP_ANONYMOUS
object. This will help you to port your applications to HP-UX and maintain source
compatibility.
•The getdtablesize (2) manpage provides information about the getdtablesize
command.
•The mkdir (2) manpage is more up to date.
Compatibility
If you choose to load only the May 2005 version of this feature, without doing a complete
update to the May 2005 version of HP-UX 11i v2, you must first load the September 2004
version of HP-UX 11i v2.
Performance
There are no known performance issues.
