aclsort - sort an ACL

SYNOPSIS

#include <sys/acl.h>

int aclsort(int nentries, int calclass, aclent_t *aclbufp);

DESCRIPTION

aclbufp points to a buffer containing ACL entries. nentries specifies the number of ACL entries in the buffer. calclass, if non-zero, indicates that the CLASS_OBJ 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.

aclsort() sorts the contents of the ACL buffer as follows:

Entries will be in the order USER_OBJ, USER, GROUP_OBJ, GROUP, CLASS_OBJ, OTHER_OBJ, DEF_USER_OBJ, DEF_USER, DEF_GROUP_OBJ, DEF_GROUP, DEF_CLASS_OBJ, and DEF_OTHER_OBJ.

Entries of type USER, GROUP, DEF_USER, and DEF_GROUP will sorted in increasing order by id.

aclsort() will succeed if all of the following are true:

There is exactly one entry each of type USER_OBJ, GROUP_OBJ, CLASS_OBJ, and OTHER_OBJ.

There is exactly one entry each of type DEF_USER_OBJ, DEF_GROUP_OBJ, DEF_CLASS_OBJ, and DEF_OTHER_OBJ if there are any default entries.

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 return value is 0. Otherwise, the return value is -1.
