+.Sh DESCRIPTION
+The
+.Fn aligned_alloc
+function allocates
+.Fa size
+bytes aligned on the specified alignment boundary
+.Fa alignment .
+The value of
+.Fa alignment
+is constrained, it must be a power of two and it must be greater than or
+equal to the size of a word on the platform.
+.Sh RETURN VALUES
+Upon successful completion, the
+.Fn aligned_alloc
+function returns a pointer to suitably aligned memory at least
+.Fa size
+bytes large. Otherwise, a
+.Sy NULL
+pointer is returned and
+.Sy errno
+is set to indicate the error.
+.Sh ERRORS
+The
+.Fn aligned_alloc
+function will fail if:
+.Bl -tag -width Er
+.It Er ENOMEM
+The physical limits of the system are exceeded by
+.Fa size
+bytes of memory which cannot be allocated.
+.It Er EAGAIN
+There is not enough memory available to allocate
+.Fa size
+bytes of memory; but the application could try again later.
+.It Er EINVAL
+An invalid value for
+.Fa alignment
+was passed in. It is not a power of two multiple of the word size.
