我一直不清楚ABI是什么。别给我指维基百科上的文章。如果我能理解，我就不会在这里发这么长的帖子了。
这是我对不同界面的看法:
电视遥控器是用户和电视之间的接口。它是一个现有的实体，但本身无用(不提供任何功能)。遥控器上每个按钮的所有功能都在电视机中实现。
Interface: It is an "existing entity" layer between the functionality and consumer of that functionality. An interface by itself doesn't do anything. It just invokes the functionality lying behind. Now depending on who the user is there are different type of interfaces. Command Line Interface (CLI) commands are the existing entities, the consumer is the user and functionality lies behind. functionality: my software functionality which solves some purpose to which we are describing this interface. existing entities: commands consumer: user Graphical User Interface(GUI) window, buttons, etc. are the existing entities, and again the consumer is the user and functionality lies behind. functionality: my software functionality which solves some problem to which we are describing this interface. existing entities: window, buttons etc.. consumer: user Application Programming Interface(API) functions (or to be more correct) interfaces (in interfaced based programming) are the existing entities, consumer here is another program not a user, and again functionality lies behind this layer. functionality: my software functionality which solves some problem to which we are describing this interface. existing entities: functions, Interfaces (array of functions). consumer: another program/application. Application Binary Interface (ABI) Here is where my problem starts. functionality: ??? existing entities: ??? consumer: ???
我用不同的语言编写过软件，并提供过不同类型的接口(CLI、GUI和API)，但我不确定是否曾经提供过ABI。
维基百科说:
abi涵盖了诸如 数据类型、大小和对齐方式; 调用约定，它控制函数的实参 传递和返回检索到的值; 系统调用编号以及应用程序应该如何进行系统调用 到操作系统; 其他abi标准化细节，如 c++名字mangling， 异常传播，以及 调用约定的编译器之间在同一平台，但做 不需要跨平台兼容性。
谁需要这些细节?请不要说操作系统。我懂汇编编程。我知道如何链接和加载工作。我知道里面发生了什么。 为什么c++会出现名字混淆?我以为我们是在谈论二元的层面。为什么会出现语言?
无论如何，我已经下载了[PDF] System V应用程序二进制接口版4.1(1997-03-18)来看看它到底包含了什么。大部分都说不通啊。
Why does it contain two chapters (4th & 5th) to describe the ELF file format? In fact, these are the only two significant chapters of that specification. The rest of the chapters are "processor specific". Anyway, I though that it is a completely different topic. Please don't say that ELF file format specifications are the ABI. It doesn't qualify to be an interface according to the definition. I know, since we are talking at such a low level it must be very specific. But I'm not sure how is it "instruction set architecture (ISA)" specific? Where can I find Microsoft Windows' ABI?
这些是困扰我的主要问题。
