+.Dt ACL_INIT 3
+.Os
+.Sh NAME
+.Nm acl_init
+.Nd initialize ACL working storage
+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.In sys/types.h
+.In sys/acl.h
+.Ft acl_t
+.Fn acl_init "int count"
+.Sh DESCRIPTION
+The
+.Fn acl_init
+function allocates and initializes the working storage for an ACL of at
+least
+.Va count
+ACL entries.
+A pointer to the working storage is returned.
+The working
+storage allocated to contain the ACL is freed by a call to
+.Xr acl_free 3 .
+When the area is first allocated, it shall contain an ACL that contains
+no ACL entries.
+.Pp
+This function may cause memory to be allocated.
+The caller should free any
+releasable memory, when the new ACL is no longer required, by calling
+.Xr acl_free 3
+with the
+.Va (void*)acl_t
+as an argument.
+.Sh IMPLEMENTATION NOTES
+.Fx Ns 's
+support for POSIX.1e interfaces and features is still under
+development at this time.
+.Sh RETURN VALUES
+Upon successful completion, this function shall return a pointer to the
+working storage.
+Otherwise, a value of
+.Va (acl_t)NULL
+shall be returned, and
+.Va errno
+shall be set to indicate the error.
+.Sh ERRORS
+If any of the following conditions occur, the
+.Fn acl_init
+function shall return a value of
+.Va (acl_t)NULL
+and set
+.Va errno
+to the corresponding value:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+The value of count is less than zero.
+.It Bq Er ENOMEM
+The
+.Va acl_t
+to be returned requires more memory than is allowed by the hardware or
+system-imposed memory management constraints.

+.Sh STANDARDS
+POSIX.1e is described in IEEE POSIX.1e draft 17.
+Discussion
+of the draft continues on the cross-platform POSIX.1e implementation
+mailing list.
+To join this list, see the
+.Fx
+POSIX.1e implementation
+page for more information.
+.Sh HISTORY
+POSIX.1e support was introduced in
+.Fx 4.0 ,
+and development continues.
