NAME

       acltomode, aclfrommode - convert an ACL to or from permission bits

SYNOPSIS

       cc [ flag... ] file... -lsec [ library... ]
       #include <sys/types.h>
       #include <sys/acl.h>

       int acltomode(aclent_t *aclbufp, int nentries, mode_t *modep);

       int aclfrommode(aclent_t *aclbufp, int nentries, mode_t *modep);

DESCRIPTION

       The  acltomode()  function  converts  an ACL pointed to by aclbufp into the permission bits buffer pointed to by modep. If the USER_OBJ ACL
       entry, GROUP_OBJ ACL entry, or the OTHER_OBJ ACL entry cannot be found in  the ACL buffer, then the function fails with errno set  to  EIN-
       VAL.

       The  USER_OBJ ACL entry permission bits are copied to the file owner class bits in the permission bits buffer. The OTHER_OBJ ACL entry per-
       mission bits are copied to the file other class bits in the permission bits buffer.   If  there	is  a  CLASS_OBJ  (ACL	mask)  entry,  the
       CLASS_OBJ  ACL  entry  permission  bits are copied to the file group class bits in the permission bits buffer. Otherwise, the GROUP_OBJ ACL
       entry permission bits are copied to the file group class bits in the permission bits buffer.

       The aclfrommode() function converts the permission bits pointed to by modep into an ACL pointed to by aclbufp. If the USER_OBJ  ACL  entry,
       GROUP_OBJ ACL entry, or the OTHER_OBJ ACL entry cannot be found in the ACL buffer, the function fails with  errno set to EINVAL.

       The  file owner class bits from the permission bits buffer are copied to the USER_OBJ ACL entry. The file other class bits from the permis-
       sion bits buffer are copied to  the OTHER_OBJ ACL entry. If there is a CLASS_OBJ (ACL mask) entry, the file group class bits from the  per-
       mission	bits  buffer  are  copied to the CLASS_OBJ ACL entry, and the GROUP_OBJ ACL entry is not modified. Otherwise, the file group class
       bits from the permission bits buffer are copied to the GROUP_OBJ ACL entry.

       The nentries argument represents the number of ACL entries in the buffer pointed to by aclbufp.

RETURN VALUES

       Upon successful completion, the function returns 0. Otherwise, it returns -1 and sets errno to indicate the error.
