When you run any C program, its executable image is loaded into the RAM of the computer in an organized manner which is called the process address space or memory layout of the C program. This memory layout is organized in the following fashion: Text or Code Segment Initialized Data Segments...

C/C++ Memory Layout 为什么需要知道C/C++的内存布局和在哪可以可以找到想要的数据?知道内存布局对调试程序非常有帮助,可以知道程序执行时,到底做了什么,有助于写出干净的代码。本文的主要内容如下: 源文件转换为可执行文件 可执行程序组成及内存布局 数据存储类别...
典型C Memory Layout 一个典型的C语言程序加载到内存中分为以下几个部分: 命令行参数 栈 堆 未初始化的数据段 有初始值的数据段 代码段 对于静态链接生成的可执行文件来说,基本就是由这六个部分组成;如果是动态链接,可能还有动态链接库加载区。关于动态链接,是一个很复杂的部分,哪天抽出时间来单独写一篇,本文...

具体到虚拟内存布局(Memory Layout),堆维护在通过brk系统调用申请的「Heap」及通过mmap系统调用申请的「Memory Mapping Segment」中;而栈维护在通过汇编栈指令动态调整的「Stack」中。在 Glibc 里,「Heap」用于分配较小的内存及主线程使用的内存。 下图为 Linux 内核 v2.6.7 之后,32 位模式下的虚拟内存布局方式。
1.4Memory layout of an executing program Computer memory consists of number of storage locations, or cells, each of which has a unique numericaddress. Addresses are usually written in hexadecimal. Each storage location can contain a fixed number ofbinary digits. The most common size is one byte...
