ERRORS
EINVAL The alignment parameter was not a power of two, or was not a
multiple of sizeof(void *).
ENOMEM There was insufficient memory to fulfill the allocation request.
NOTES
posix_memalign() verifies that alignment matches the requirements
detailed above. memalign() may not check that the boundary parameter is
correct.
