What is the replacement in C++ for _aligned_malloc in C?

[Amal P]

Hi,

I want to allocate some memory 16Byte aligned. For this now I am
using _aligned_malloc function that is given in malloc.h. What is the
substitute for this in new ? Is there any way to allocate aligned
memory using new ?

Thanks and Regards,
Amal P.

_aligned_malloc is not a Standard function, but rather an extension
provided by your implementation. You should probably continue using that
extension function.

You can take a look at this usage of new called
"placement new"...

new (placement_addr) type;

where placement_addr is compulsorily a pointer!

But yes, you need to say delete placement_addr & not the type pointer
used in "new".
