except for the CAVEATS documented below.

VERSIONS
On some systems
memalign()
is declared in
<stdlib.h>
instead of
<malloc.h>.
STANDARDS
None.
HISTORY
glibc 2.0.
SunOS 4.1.3.
CAVEATS
memalign()
may not check that the
alignment
argument is correct.
Some systems provide no way to reclaim memory allocated with
memalign()
(because one can pass to
free(3)
only a pointer obtained from
malloc(3),
while, for example,
memalign()
would call
malloc(3)
and then align the obtained value).
The glibc implementation
allows memory obtained from
memalign()
to be reclaimed with
free(3).
