Versions
On some systems memalign() is declared in <stdlib.h> instead of <malloc.h>.
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).
