29.Sh NAME
30.Nm acl_from_mode_np
31.Nd create an ACL from status information
32.Sh LIBRARY
33.Lb libc
34.Sh SYNOPSIS
35.In sys/types.h
36.In sys/acl.h
37.Ft acl_t
38.Fn acl_from_mode_np "const mode_t mode"
39.Sh DESCRIPTION
40The
41.Fn acl_from_mode_np
42function is a non-portable call that converts the permissions set referred to by
43.Va mode
44into the corresponding minimal ACL structure, appropriate for applying to
45files or manipulating.
46.Pp
47This function causes memory to be allocated.
48The caller should free any
49free-able memory, when the new ACL is no longer required, by calling
50.Xr acl_free 3
51with the
52.Va (void *)acl_t
53as an argument.
54.Sh RETURN VALUES
55Upon successful completion, the function returns a pointer to the
56internal representation of the ACL in working storage.
57Otherwise, a value
58of
59.Va (acl_t)NULL
60is returned, and
61.Va errno
62is set to indicate the error.
63.Sh ERRORS
64If any of the following conditions occur, the
65.Fn acl_from_mode_np
66function returns a value of
67.Va (acl_t)NULL
68and set
69.Va errno
70to the corresponding value:
71.Bl -tag -width Er
72.It Bq Er ENOMEM
73The ACL working storage requires more memory than is allowed by the
74hardware or system-imposed memory management constraints.

82POSIX.1e is described in IEEE POSIX.1e draft 17.
83Discussion
84of the draft continues on the cross-platform POSIX.1e implementation
85mailing list.
