What is the difference between memmove and memcpy?

What is the difference between memmove and memcpy ? Which one do you usually use and how? With memcpy , the destination cannot overlap the source at all. With memmove it can. This means that memmove might be very slightly slower than memcpy , as it cannot make the same assumptions. For example, memcpy might always copy addresses from low to high. If the destination overlaps after the sour

memmove和memcpy有什么区别?

memmove和memcpy什么区别? 你通常使用哪一个以及如何? 使用memcpy ,目标无法与源重叠。 随着memmove它可以。 这意味着memmove可能会比memcpy慢一点,因为它不能做出相同的假设。 例如, memcpy可能总是将地址从低到高复制。 如果目标在源之后重叠,这意味着某些地址在复制之前将被覆盖。 memmove会检测到这一点,并在另一个方向上复制 - 从高到低 - 在这种情况下。 但是,检查这个并切换到另一个(可能效率较低)算

Before I'm going to reinvent the wheel I thought of asking here first. Any hints about an implementation strategy are greatly appreciated! Example The Monorailcat --------------- ![Picture of a L

Connect Azure Website to Xero Partner Application

I'm integrating my app with Xero which requires two certificates. I uploaded them to Azure with help from this article, but I'm still unable to connect to the Xero API. I'm hoping someone has experience integrating a Xero Partner Application with an Azure Web App. I've uploaded two pfx files; one is a self-signed certificate and the other is the partner certificate issued by

将Azure网站连接到Xero合作伙伴应用程序

我正在将我的应用程序与需要两个证书的Xero集成。 在本文的帮助下,我将它们上传到了Azure,但我仍无法连接到Xero API。 我希望有人将Xero合作伙伴应用程序与Azure Web App集成在一起。 我已经上传了两个pfx文件; 一个是自签名证书,另一个是Xero颁发的合作伙伴证书。 后者的pfx文件包含两个证书; 一个Entrust商业私人小组CA1(无论如何)和一个独特的Entrust Id证书为我的应用程序。 我正在使用以下代码通过其独特的指

How to create a generic timeout object for various code blocks?

I have a series of code blocks that are taking too long. I don't need any finesse when it fails. In fact, I want to throw an exception when these blocks take too long, and just fall out through our standard error handling. I would prefer to NOT create methods out of each block (which are the only suggestions I've seen so far), as it would require a major rewrite of the code base. Her

如何为各种代码块创建通用超时对象?

我有一系列代码块耗时太长。 失败时我不需要任何技巧。 事实上,当这些块花费太长时间时,我想抛出一个异常,并通过我们的标准错误处理而退出。 我宁愿不从每个块中创建方法(这是我目前看到的唯一建议),因为它需要对代码库进行重大改写。 这是我想如果可能的创建。 public void MyMethod( ... ) { ... using (MyTimeoutObject mto = new MyTimeoutObject(new TimeSpan(0,0,30))) { // Everything in

How can I convert a Number.Double Access column value to a Decimal?

Since decimal is preferable to double for monetary values (see David's answer here), I am trying to change my code to use decimal instead of double. IOW, I changed this: public class InventoryItem { . . . public double UnitCost { get; set; } public double UnitList { get; set; } public double OpenQty { get; set; } . . . ...to this: public class InventoryItem { . . . public

如何将Number.Double Access列值转换为Decimal?

由于小数对于货币值更好(请参阅David的答案),所以我试图将我的代码更改为使用小数而不是double。 IOW,我改变了这一点: public class InventoryItem { . . . public double UnitCost { get; set; } public double UnitList { get; set; } public double OpenQty { get; set; } . . . ...对此: public class InventoryItem { . . . public decimal UnitCost { get; set; } public decimal UnitList {

Multiple types were found that match the controller named 'Home'

I currently have two unrelated MVC3 projects hosted online. One works fine, the other doesn't work, giving me the error: Multiple types were found that match the controller named 'Home'. This can happen if the route that services this request ('{controller}/{action}/{id}') does not specify namespaces to search for a controller that matches the request. If this is the ca

发现多个类型与名为'Home'的控制器匹配

我目前有两个不相关的MVC3项目在线托管。 一个正常工作,另一个不起作用,给我错误: 发现多个类型与名为'Home'的控制器相匹配。 如果为该请求提供服务的路由('{controller} / {action} / {id}')没有指定命名空间来搜索与该请求匹配的控制器,就会发生这种情况。 如果是这种情况,请通过调用带有'namespaces'参数的'MapRoute'方法的重载来注册此路由。 我的托管人的工作方式是他给了

Why c# decimals can't be initialized without the M suffix?

public class MyClass { public const Decimal CONSTANT = 0.50; // ERROR CS0664 } produces this error: error CS0664: Literal of type double cannot be implicitly converted to type 'decimal'; use an 'M' suffix to create a literal of this type as documented. But this works: public class MyClass { public const Decimal CONSTANT = 50; // OK } And I wonder why they for

为什么没有M后缀,c#小数不能被初始化?

public class MyClass { public const Decimal CONSTANT = 0.50; // ERROR CS0664 } 产生这个错误: 错误CS0664:文字类型double不能隐式转换为类型'decimal'; 使用'M'后缀来创建这种类型的文字 如文件所述。 但是这工作: public class MyClass { public const Decimal CONSTANT = 50; // OK } 我想知道他们为什么禁止第一个。 这对我来说似乎很奇怪。 没有m后缀的文字类型是double -

How to implement Continuous Delivery with DNX and ASP.NET 5

I have been working on .net platform for few years now and I must say I am very impressed by how Microsoft is making .net cross-platform compatible. I spent hours trying to run a small hello world application built using CoreCLR on a mac. And it worked. While There are still a lot of UNKNOWNS I am still trying to understand, there is this one question I was not able to find answer of on googl

如何使用DNX和ASP.NET 5实现持续交付

我已经在.NET平台上工作了好几年了,我必须说,我对Microsoft如何使.net跨平台兼容印象深刻。 我花了好几个小时试图运行在Mac上使用CoreCLR构建的小型Hello World应用程序。 它的工作。 虽然仍有很多UNKNOWNS我仍在试图了解,但有一个问题我无法在google上找到答案。 你如何自动部署一个DNX应用程序。 我的意思是,你是否将你的aspnet 5应用程序编译成nuget包,然后在你的linux服务器上恢复它(我从来没有用过linux,所以

Reliably compare type symbols (ITypeSymbol) with Roslyn

I am trying to reliably compare two instances of ITypeSymbol the easiest and most straight forward way possible in the following situation (I came across these issues in a bigger project and tried to simplify it as much as possible): I have got a CSharpCompilation with this SyntaxTree: namespace MyAssembly { public class Foo { public Foo(Foo x) { } } } We a

可靠地比较类型符号(ITypeSymbol)和Roslyn

我试图在以下情况下可靠地比较两个ITypeSymbol实例, ITypeSymbol是最简单也是最直接的方式(我在一个更大的项目中遇到了这些问题,并试图尽可能简化它): 我用这个SyntaxTree得到了一个CSharpCompilation: namespace MyAssembly { public class Foo { public Foo(Foo x) { } } } 我们用CSharpSyntaxRewriter遍历树,更改类并更新Compilation 。 在第一次运行中,我们记得第一个构造

In POSIX, can a main(void) recover command line arguments?

In C, is int main(int argc, char *argv[]) really needed to receive program arguments? In other words, when defining the main function with the signature int main(void) , is it possible to recover the program arguments using only POSIX interfaces? I feel like I'm missing something, seeing that: POSIX defines multiple interfaces to retrieve other process-specific information. For instance

在POSIX中,可以使用主(void)恢复命令行参数吗?

在C中, int main(int argc, char *argv[])真的需要接收程序参数? 换句话说,当使用签名int main(void)定义主函数时,是否可以仅使用POSIX接口来恢复程序参数? 我觉得我错过了一些东西,看到: POSIX定义了多个接口来检索其他特定于进程的信息。 例如,有环境变量的接口(可以继承自C99,但也可以使用unsetenv() )和主机标识( gethostid() )等函数进行扩展。 特定的操作系统定义了检索命令行参数的“全局”方法。 例
