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.
