Dynamic aligned memory allocation in C++11 http://stackoverflow.com/questions/6973995/dynamic-aligned-memory-allocation-in-c11 It depends on what alignment you require. For anything to alignof std max_align_t new works as per n3242 3.7.4.1 2 The pointer.. 1. As for allocating memory with an alignment greater than alignof std max_align_t C 11 provides no direct way to do this. The.. only reliable way is to allocate at least size alignment alignof std max_align_t bytes and use std align to get a correctly aligned..
