ACLSORT(3SEC)ACLSORT(3SEC)NAME
aclsort - sort an ACL
SYNOPSIS
cc [ flag ... ] file ... -lsec [ library ... ]
#include <sys/acl.h>
int aclsort(int nentries, int calclass, aclent_t *aclbufp);
DESCRIPTION
The aclbufp argument points to a buffer containing ACL entries. The
nentries argument specifies the number of ACL entries in the buffer.
The calclass argument, if non-zero, indicates that the CLASS_OBJ (ACL
mask) permissions should be recalculated. The union of the permission
bits associated with all ACL entries in the buffer other than
CLASS_OBJ, OTHER_OBJ, and USER_OBJ is calculated. The result is copied
to the permission bits associated with the CLASS_OBJ entry.
The aclsort() function sorts the contents of the ACL buffer as follows:
o Entries will be in the order USER_OBJ, USER, GROUP_OBJ,
GROUP, CLASS_OBJ (ACL mask), OTHER_OBJ, DEF_USER_OBJ,
DEF_USER, DEF_GROUP_OBJ, DEF_GROUP, DEF_CLASS_OBJ (default
ACL mask), and DEF_OTHER_OBJ.
o Entries of type USER, GROUP, DEF_USER, and DEF_GROUP will be
sorted in increasing order by ID.
The aclsort() function will succeed if all of the following are true:
o There is exactly one entry each of type USER_OBJ, GROUP_OBJ,
CLASS_OBJ (ACL mask), and OTHER_OBJ.
o There is exactly one entry each of type DEF_USER_OBJ,
DEF_GROUP_OBJ, DEF_CLASS_OBJ (default ACL mask), and
DEF_OTHER_OBJ if there are any default entries.
o Entries of type USER, GROUP, DEF_USER, or DEF_GROUP may not
contain duplicate entries. A duplicate entry is one of the
same type containing the same numeric ID.
RETURN VALUES
Upon successful completion, the function returns 0. Otherwise, it
returns −1.
