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"

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 function will return in
52.Fa entry_p
53a descriptor for this ACL entry.

54.Pp
55The
56.Fn acl_create_entry_np
57function is a non-portable extension which allows the caller to specify the
58position of the created entry within the ACL. If
59.Fa entry_index
60is
61.Dv ACL_FIRST_ENTRY
62the entry will be created at the head of the ACL. If
63.Fa entry_index
64is
65.Dv ACL_LAST_ENTRY
66the entry will be created at the end of the ACL. After inserting an ACL entry with an
67.Fa entry_index
68other than
69.Dv ACL_LAST_ENTRY
70the behaviour of any acl_entry_t's previously obtained from the ACL
71by
72.Fn acl_create_entry
73or
74.Fn acl_get_entry
75is undefined.
76.Sh RETURN VALUES
77.Rv -std acl_create_entry
78.Sh ERRORS
79The
80.Fn acl_create_entry
81and
82.Fn acl_create_entry_np
83functions fail if:
84.Bl -tag -width Er
85.It Bq Er EINVAL
86Argument
87.Fa acl_p
88does not point to a pointer to a valid ACL.
89.It Bq Er ENOMEM
90The ACL working storage requires more memory than is
91allowed by the hardware or system-imposed memory
92management constraints.
93.It Bq Er ERANGE
94The
95.Fa entry_index
96argument to
97.Fn acl_create_entry_np
98is greater than the number of entries in the ACL.
