malloc(memory allocation):用于从堆内存中分配指定大小的字节块,其返回值需强制转换为适当的指针类型。 calloc(contiguous allocation):类似于malloc,但它为数组分配内存并初始化为零。 allocator:C++ STL 中的一种模板类,提供灵活的内存分配策略。 工作流程 请求内存:通过调用malloc或calloc请求内存。 检查分配结果:判...

pool_allocator G2.9 容器使用的分配器不是 std::allocator 而是 std::alloc (缺点,只申请不归还) G4.9 中的进化 G4.9 标准库中有许多 extented allocators, 其中 __pool_alloc 就是 G2.9 的化身 #include <iostream> #include <cstddef> #include <memory> //內含 std::allocator #include <ext\pool_al...

Memory pool allocator. C / C++. Optimized for quick alloc, realloc, free. The allocated memory is always16 bytes aligned. You can use DKMalloc for your project. Build DKMalloc as a shared library / DLL for C projects that can not use C++. ...
第四讲:loki::allocator 即使知名如 GNU C++ pool allocator, 也有其小缺陷。Loki(一套作风前沿的程序库)的 allocator 设计精简功能完整几无缺点,很值得我们深究。 上中下三个 classes 分析 Loki::allocator 行为图解 class Chunk 分析 class FixedAllocator 分析 ...
