ACLs on JFS 3.3

[Peter Gemsjaeger]

In order to support ACLs of the JFS 3.3 file system on HP-UX 11.00, (downloaded JFS 3.3 version) Installation and upgrading the JFS file systems to layout 4 was ok, I was able to set and read acls, using setacl and getacl commands.
But to use the acl(2) and aclsort(2) system calls within an application, I could not link them. I only found the man pages for these functions. I also found /usr/include/sys/aclv.h include file, but not /usr/include/aclv.h (which I guess, should also contain the acl() prototype).
Where do I find /usr/include/aclv.h and the according library for the system calls?
