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).
