is due to the fact that the memory pages allocated for each size class is split up in perfectly aligned blocks which are not reused for a request of a different size. The block freed by a call torpfreewill always be immediately available for an allocation request within the same size ...
动态内存分配 (Dynamic memory allocation ) 任何动态分配的数组或对象(使用 new 或 malloc)都必须通过指针访问。对于程序员来说,指向不同动态分配对象的指针可能很明显没有重叠或别名,但编译器通常无法看到这一点。它还可能阻止编译器以最佳方式对齐数据,或者不知道对象已对齐。在需要它们的函数中声明对象和固定大小的...
mallocreturns a void pointer to the allocated space, orNULLif there is insufficient memory available. To return a pointer to a type other thanvoid, use a type cast on the return value. The storage space pointed to by the return value is guaranteed to be suitably aligned for storage of any...

Aligned allocation functions In previous versions, the aligned allocation functions (_aligned_malloc, _aligned_offset_malloc, etc.) would silently accept requests for a block with an alignment of 0. The requested alignment must be a power of two, which isn't true of zero. A requested alignment...
