aclsort(3SEC)	     File Access Control Library Functions	 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  con-
	    tain  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  re-
       turns -1.
