Removing internal symbols from C static library

I'm working on some embedded code that is shipped as a static library. We would like to remove all internal symbols from the library and keep only the API symbols visible. Here's an example of what we want to do: imagine that you have a file called internal.c and one called api.c that look like that: /* internal.c */ int fibonacci(int n) { /* Compute the nth Fibonacci number and

从C静态库中删除内部符号

我正在研究一些作为静态库提供的嵌入式代码。 我们希望从库中删除所有内部符号,并只保留API符号可见。 下面是我们想要做的一个例子:想象一下你有一个名为internal.c的文件,一个名为api.c的文件如下所示: /* internal.c */ int fibonacci(int n) { /* Compute the nth Fibonacci number and return it */ } /* api.c */ #include "internal.h" #include <stdio.h> void print_fibonacci(n) { printf("F

Cacheable SSL page found, Bundling and Minification

We have an MVC application that is scanned for security issues by a third party company using IBM app scan. The problem is that we have multiple issues raised because of Bundling and Minification, for example The entire point is that bundling and minification will cache your stylesheets and javascript files. Unfortunately we will not get sign off without resolving these issues. Any ideas on

发现缓存SSL页面,捆绑和缩小

我们有一个MVC应用程序,使用IBM应用程序扫描由第三方公司扫描安全问题。 问题是,例如,由于捆绑和缩小导致出现多个问题 整个观点是捆绑和缩小会缓存你的样式表和JavaScript文件。 不幸的是,如果不解决这些问题,我们不会签字。 有关我们如何克服这个问题的想法? 不幸的是,客户端不会接受他的CSS和JavaScript文件被缓存的事实,并要求禁用所有缓存,从而解决了所有问题。 为了达到这个目的,我在Global.asax文件中

Guid.NewGuid() vs. new Guid()

What's the difference between Guid.NewGuid() and new Guid() ? Which one is preferred? new Guid() makes an "empty" all-0 guid (00000000-0000-0000-0000-000000000000 is not very useful). Guid.NewGuid() makes an actual guid with a unique value, what you probably want. Guid.NewGuid() creates a new UUID using an algorithm that is designed to make collisions very, very unlikely.

Guid.NewGuid()与新的Guid()

Guid.NewGuid()和new Guid()什么区别? 哪一个是首选? new Guid()使得一个“空”全0的guid(00000000-0000-0000-0000-000000000000不是很有用)。 Guid.NewGuid()用一个独特的价值做出了一个实际的指导,你可能想要的。 Guid.NewGuid()使用一种算法来创建一个新的UUID,该算法旨在使碰撞非常非常不可能。 new Guid()创建一个全零的UUID。 一般来说,你会喜欢前者,因为这是UUID的要点(除非你从其他地方接收它)。

C# how to create a Guid value?

One field of our struct is Guid type. How to generate a valid value for it?

C#如何创建一个Guid值?

我们的结构的一个字段是Guid类型。 如何为其生成有效值? Guid id = Guid.NewGuid(); Guid.NewGuid()创建一个新的随机guid。 有两种方法 var guid = Guid.NewGuid(); 要么 var guid = Guid.NewGuid().ToString(); 都使用Guid类,第一个创建Guid对象,第二个是Guid字符串。

Could not establish trust relationship for SSL/TLS secure channel

I have a simple web service call, generated by a .NET (C#) 2.0 windows app, via the web service proxy generated by Visual Studio, for a web service also written in C# (2.0). This has worked for several years, and continues to do so at the dozen or so places where it is running. A new installation at a new site is running into a problem. When attempting to invoke the web service, it fails with

无法建立SSL / TLS安全通道的信任关系

我有一个简单的Web服务调用,由.NET(C#)2.0 Windows应用程序通过由Visual Studio生成的Web服务代理生成,也用于使用C#(2.0)编写的Web服务。 这已经工作了好几年,并且在它正在运行的十几个地方继续这样做。 新网站的新安装会遇到问题。 尝试调用Web服务时,它会失败,并显示以下消息: 无法建立SSL / TLS安全通道的信任关系 该Web服务的URL使用SSL(https://) - 但它已经在许多其他位置上工作了很长时间(并继续

Capture and edit TCP/UDP Packets

I'm trying to create a tool, which would append/edit something inside specific packets, before they get sent to the specific website. For now I was using Wpe Pro to apply this filter. Is there something similar in C# to create this tool? There is not really a general way to do this. There are multiple possibilities you have to consider and see if they fit your situation. For example y

捕获和编辑TCP / UDP数据包

我正在尝试创建一个工具,在特定数据包发送到特定网站之前,它会在特定数据包中追加/编辑某些内容。 现在我正在使用Wpe Pro来应用此过滤器。 C#中是否有类似的东西来创建这个工具? 实际上并没有一个通用的方法。 你需要考虑多种可能性,看看它们是否适合你的情况。 例如,您可以通过使用Pcap.NET(如注释中所述)轻松地编辑使用HTTP发送的数据包。 网络上有几十个例子可以指导你使用Pcap修改数据包,例如在官方Pcap.N

How to determine the minimal required .NET framework version to run my app

I have written c# console app. .NET Framework is by default set to version 4.5. I want to know if there is a way, to test app with older versions of .NET framework or test, which version of framework app actually needs to run( without regarding targettype framework). You can add some entries to your app.config file to target a particular version of the framework, to override the version that

如何确定运行我的应用程序所需的最小.NET框架版本

我写了c#控制台应用程序。 .NET Framework默认设置为版本4.5。 我想知道是否有办法,用旧版本的.NET框架或测试测试应用程序,哪个版本的框架应用程序实际需要运行(不考虑目标类型框架)。 您可以将一些条目添加到您的app.config文件中,以定位特定版本的框架,以覆盖其构建的版本。 显然你仍然需要测试它是否适用于这些版本,但是这可以让你在不同版本的框架上运行: <configuration> <!-- this is used if th
