Name

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.
