C++ 中偏好的内存分配方法是用 RAII 就绪的函数 std::make_unique、std::make_shared、容器构造函数等,而在低层代码中为 new 表达式。 对于加载大文件,经由如 POSIX 上的 mmap 或Windows 上的 CreateFileMapping(A/W) 伴随 MapViewOfFile 的操作系统特定函数进行文件映射,比为文件读取分配缓冲区更适合。

Likestd::make_shared, this function typically performs only one allocation, and places both theTobject and the control block in the allocated memory block (the standard recommends but does not require this, all known implementations do this). A copy ofallocis stored as part of the control blo...
