36.In sys/types.h
37.In sys/acl.h
38.Ft int
39.Fn acl_create_entry "acl_t *acl_p" "acl_entry_t *entry_p"

41.Fn acl_create_entry_np "acl_t *acl_p" "acl_entry_t *entry_p" "int index"
42.Sh DESCRIPTION
43The
44.Fn acl_create_entry
45function
46is a POSIX.1e call that creates a new ACL entry in the ACL
47pointed to by
48.Fa acl_p .
49The
50.Fn acl_create_entry_np
51function is a non-portable version that creates the ACL entry
52at position
53.Fa index .
54Positions are numbered starting from zero, i.e. calling
55.Fn acl_create_entry_np
56with
57.Fa index
58argument equal to zero will prepend the entry to the ACL.

69does not point to a pointer to a valid ACL.
70Argument
71.Fa index
72is out of bounds.
73.It Bq Er ENOMEM

75allowed by the hardware or system-imposed memory
76management constraints.
