37.Sh SYNOPSIS
38.In sys/types.h
39.In sys/acl.h
40.Ft int
41.Fn acl_create_entry "acl_t *acl_p" "acl_entry_t *entry_p"
42.Ft int
43.Fn acl_create_entry_np "acl_t *acl_p" "acl_entry_t *entry_p" "int index"
44.Sh DESCRIPTION
45The
46.Fn acl_create_entry
47function
48is a POSIX.1e call that creates a new ACL entry in the ACL
49pointed to by
50.Fa acl_p .
51The
52.Fn acl_create_entry_np
53function is a non-portable version that creates the ACL entry
54at position
55.Fa index .
56Positions are numbered starting from zero, i.e. calling
57.Fn acl_create_entry_np
58with
59.Fa index
60argument equal to zero will prepend the entry to the ACL.
61.Sh RETURN VALUES
62.Rv -std acl_create_entry
63.Sh ERRORS

71does not point to a pointer to a valid ACL.
72Argument
73.Fa index
74is out of bounds.
75.It Bq Er ENOMEM

77allowed by the hardware or system-imposed memory
78management constraints.
