C中的内存段-文本段 [英] Memory Segments in C — Text Segment

问题描述

有人可以告诉我C语言中的文本段"是什么，如果可以的话，请给我看一个简单的示例?

Can someone tell me what is a 'text segment' in C, and if possible show me a simple example?

推荐答案

Unix系统上程序的文本"段是代码—机器代码，组成程序的功能(尤其包括main()(如果程序是用C或C ++编写的).它还可以包含只读数据.经典程序中的其他段是数据"段和"bss"段. 数据"段保存初始化的数据； "bss"段保存归零的数据.运行后，数据段和bss段将无法区分.

The 'text' segment of a program on Unix systems is the code — the machine code, the functions that make up the program (including, in particular, main() if the program is written in C or C++). It can also include read-only data. The other segments in a classic program are the 'data' segment and the 'bss' segment. The 'data' segment holds initialized data; the 'bss' segment holds zeroed data. Once running, the data and bss segments are indistinguishable.

您还最终得到了堆栈和堆".

You also end up with the stack and 'the heap'.
