編譯器錯誤 C2346 'function' 無法編譯為原生:原因 編譯程式無法將函式編譯成 MSIL。 如需詳細資訊,請參閱Managed、Unmanaged和/clr (Common Language Runtime Compilation)。 範例 下列範例會產生 C2346。
Memory addresses are specified using brackets, in units of four bytes. Programs running within the virtual machine have their own address space, so no positive address within the address space is off limits. It is important to note that certain areas of memory are used for vital program functi...
另外和Intel VT相关的几个技术,最好也能够支持,其中包括Intel® Virtualization Technology for Directed I/O (VT-d)和Intel® VT-x with Extended Page Tables (EPT),这两个技术能够在处理IO请求和页表映射时提供加速能力,可以作为高级功能进行探索和学习。 处理最基本的配置,这里列出作者在编写本书时用到的...
ASan,即Address Sanitizer,是一个适用于c/c++程序的动态内存错误检测器,它由一个编译器检测模块(LLVM pass)和一个替换malloc函数的运行时库组成,在性能及检测内存错误方面都优于Valgrind,你值得拥有。 一 适用平台 在LLVM3.1版之后,ASan就是其的一个组成部分,所以所有适用LLVM的平台,且llvm版本大于...
