检查大量的返回值时，优秀的C风格 [英] good c style when checking lots of return values

问题描述

有时候，我不得不写code，它做的事情，并检查错误条件之间交替（例如，调用库函数，检查其返回值，继续下去）。这往往导致长期运行的实际工作中的if语句的条件发生，像

Sometimes I have to write code that alternates between doing things and checking for error conditions (e.g., call a library function, check its return value, keep going). This often leads to long runs where the actual work is happening in the conditions of if statements, like

if(! (data = (big_struct *) malloc(sizeof(*data)))){
    //report allocation error
} else if(init_big_struct(data)){
    //handle initialization error
} else ...

你们怎么写这种code的？我检查了几个风格指南，但他们似乎更关心的变量命名和空格。

How do you guys write this kind of code? I've checked a few style guides, but they seem more concerned with variable naming and whitespace.

编辑：如果现在还不清楚，我不满意这种风格的易读性，并寻找更好的东西。

in case it's not clear, I'm dissatisfied with the legibility of this style and looking for something better.

虽然它的痛苦，我说，这可能是永不受欢迎的转到的情况。这里有一个链接，我发现关于这个问题：<一href=\"http://eli.thegreenplace.net/2009/04/27/using-goto-for-error-handling-in-c/\">http://eli.thegreenplace.net/2009/04/27/using-goto-for-error-handling-in-c/

Though it pains me to say it, this might be a case for the never-popular goto. Here's one link I found on on the subject: http://eli.thegreenplace.net/2009/04/27/using-goto-for-error-handling-in-c/
