acl_add_perm
— add
permissions to a permission set
Standard C Library (libc, -lc)
#include
<sys/types.h>
#include <sys/acl.h>
int
acl_add_perm
(acl_permset_t
permset_d, acl_perm_t
perm);
The
acl_add_perm
()
function is a POSIX.1e call that adds the permission contained in
perm to the permission set
permset_d.
Note: it is not considered an error to attempt to add permissions that already exist in the permission set.
The acl_add_perm
() function returns the
value 0 if successful; otherwise the value -1 is returned and
the global variable errno is set to indicate the
error.
The acl_add_perm
() function fails if:
EINVAL
]acl(3), acl_clear_perms(3), acl_delete_perm(3), acl_get_permset(3), acl_set_permset(3), posix1e(3)
POSIX.1e is described in IEEE POSIX.1e draft 17.
