I have a C++ structure below: struct CTMDeviceError { struct CTMDeviceInfo sDeviceInfo; int32_t iResultCode; int32_t iExtendedResultCode; int32_t * piDenomination; int32_t * piChangeDue; }; I have created an equivalent c# structure but I'm having trouble marshalling the int32 * type. [StructLayout(LayoutKind.Sequential)] p
我有一个C ++结构如下： struct CTMDeviceError { struct CTMDeviceInfo sDeviceInfo; int32_t iResultCode; int32_t iExtendedResultCode; int32_t * piDenomination; int32_t * piChangeDue; }; 我创建了一个等效的c＃结构，但是我无法编组int32 *类型。 [StructLayout(LayoutKind.Sequential)] public struct CTMDeviceError { public CTMDeviceI
i was wondering how to marshall string types to BSTR* types. just to elaborate, the C++ structure is as follows: struct MyStruct { BSTR* string; int a; } i need to define a new sturct in C# side, i tried both string[] and IntPtr[] but that didn't come up with a success. Thanks for your help! edit: c++ structure: struct HTTPTEXTRENDERERFILTERINFO { enum { UTC, GMT
我想知道如何将字符串类型编组为BSTR *类型。 只是为了阐述，C ++结构如下： struct MyStruct { BSTR* string; int a; } 我需要在C＃端定义一个新的sturct，我尝试了string []和IntPtr []，但没有成功。 谢谢你的帮助！ 编辑：c ++结构： struct HTTPTEXTRENDERERFILTERINFO { enum { UTC, GMT } eTimestamp; BOOL bEnableCCIngest; LONG lQueueSizeTreshold; LONG
I'm in the process of rewriting an overengineered and unmaintainable chunk of my company's library code that interfaces between C# and C++. I've started looking into P/Invoke, but it seems like there's not much in the way of accessible help. We're passing a struct that contains various parameters and settings down to unmanaged codes, so we're defining identical structs.
我正在重写我公司的库代码的过度工程和不可维护的块，这些代码在C＃和C ++之间进行接口。 我已经开始研究P / Invoke，但是看起来好像没有什么可访问的帮助。 我们将包含各种参数和设置的结构传递给非托管代码，因此我们正在定义相同的结构。 我们不需要在C ++端更改任何这些参数，但我们需要在P / Invoked函数返回后访问它们。 我的问题是： 什么是传递字符串的最佳方式？ 有些是短的（设备ID可以由我们设置），有些是
I am having a struct defined in C++ which contains int and std::string arrays which is a native C++ code (dll). I have used following method to get it in C#: public class PInvokeData { [StructLayout(LayoutKind.Sequential)] public struct pinvoke_call { //[MarshalAs(UnmanagedType.LPArray,SizeConst=5,SizeParamIndex=0,MarshalType="int")] [MarshalAs(UnmanagedType.
我有一个在C ++中定义的结构，它包含int和std :: string数组，这是一个本地C ++代码（dll）。 我用下面的方法在C＃中获取它： public class PInvokeData { [StructLayout(LayoutKind.Sequential)] public struct pinvoke_call { //[MarshalAs(UnmanagedType.LPArray,SizeConst=5,SizeParamIndex=0,MarshalType="int")] [MarshalAs(UnmanagedType.ByValArray, SizeConst=5)]//,SizeParamInd
For all you compiler gurus, I wanna write a recursive descent parser and I wanna do it with just code. No generating lexers and parsers from some other grammar and don't tell me to read the dragon book, i'll come around to that eventually. I wanna get into the gritty details about implementing a lexer and parser for a reasonable simple language, say CSS. And I wanna do this right. T
对于你所有的编译器大师，我想写一个递归下降解析器，我想用代码来完成。 没有从其他语法生成词法分析器和解析器，也不会告诉我阅读龙书，我会最终回答这个问题。 我想深入了解一个合理的简单语言实现一个词法分析器和解析器的细节，比如说CSS。 我想这样做是正确的。 这可能最终会成为一系列问题，但现在我以一个词法分析器开始。 在这里可以找到CSS的令牌化规则。 我发现我的自我编写代码是这样的（希望你可以从这段
I am writing a raytracer as a part of my complete 3d engine. I am planning on using javascript for the scripting language instead of writing my own. The question is how can I use it? Btw the raytracer and the UI are written in C#. This shows the two-way interaction between Javascript and c#. Javascript calls ac# method C# gets the result of an expression in Javascript - Type scriptTyp
我正在写一个raytracer作为我的完整3d引擎的一部分。 我正在计划将JavaScript用于脚本语言，而不是编写自己的脚本语言。 问题是我该如何使用它？ 顺便说一句，raytracer和用户界面是用C＃编写的。 这显示了Javascript和c＃之间的双向交互。 JavaScript调用ac＃方法 C＃在Javascript中获取表达式的结果 - Type scriptType = Type.GetTypeFromCLSID(Guid.Parse("0E59F1D5-1FBE-11D0-8FF2-00A0D10038BC")); dynamic o
I have a data source that is comma-delimited, and quote-qualified. A CSV. However, the data source provider sometimes does some wonky things. I've compensated for all but one of them (we read in the file line-by-line, then write it back out after cleansing), and I'm looking to solve the last remaining problem when my regex-fu is pretty weak. Matching a Quoted String inside of another
我有一个逗号分隔和引用限定的数据源。 CSV。 但是，数据源提供者有时会做一些不起眼的事情。 我已经补偿了除了其中一个之外的所有人（我们逐行读入文件，然后在清洗后将其写回），并且当我的正则表达式相当弱时，我正在寻求解决最后剩下的问题。 匹配另一个引用字符串中的引用字符串 所以这里是我们的示例字符串... "foobar", 356, "Lieu-dit "chez Métral", Chilly, FR", "-1,000.09", 467, "barfoo", 1,345,456,235,23
I am trying to capture the command line arguments of all running processes. Some of these processes have command lines that exceed the 4096 character limit of /proc/${pid}/cmdline, so reading that procfs file does not meet my requirement. The processes that interest me can be transient, so I need to be able to read their command line arguments from the stack in /proc/${pid}/mem as soon as I bec
我正在尝试捕获所有正在运行的进程的命令行参数。 其中一些进程的命令行超过了/ proc / $ {pid} / cmdline的4096个字符限制，因此读取该procfs文件不符合我的要求。 我感兴趣的进程可能是暂时的，所以我需要能够在我意识到它们的pid时立即从/ proc / $ {pid} / mem中的堆栈读取它们的命令行参数。 这需要在我的C代码中附加ptrace。 while (pid >= 0){ intPtraceReturnValue = ptrace(PTRACE_ATTACH,pid,NULL,NULL);
I've been playing with ptrace to see if I can modify the value of simple global integers in a C program. I know that I can use PEEKDATA and POKEDATA to accomplish this. However, these need information about where the variable is stored in memory in order to function. All the tutorials I've googled for seem to suggest the most popular way to do this is by using nm or objdump manually to
我一直在玩ptrace ，看看我是否可以在C程序中修改简单全局整数的值。 我知道我可以使用PEEKDATA和POKEDATA来实现这一点。 但是，这些需要有关变量存储在内存中以便运行的信息。 我所搜索的所有教程似乎都表明，最流行的方法是手动使用nm或objdump来获取此地址。 有没有办法做到这一点，而不需要事先知道变量地址甚至变量名称（如下所示）： int i=0; //Assume i is defined globally and is the first integer defined in th
I'm writing a program that monitors system calls ( among other things ). But I'm having some trouble getting ptrace to recognize the process ID that I'm passing to it. Upon executing the program, I get this error message: :No such process However, I have verified the process ID right before the call by printing it to the console and verifying it with ps -all . Here's some of
我正在编写一个程序来监视系统调用（除其他外）。 但是我在使用ptrace识别我传递给它的进程ID方面遇到了一些麻烦。 执行该程序后，我收到以下错误消息： :No such process 但是，我已在调用之前通过将其打印到控制台并使用ps -all验证来验证进程ID。 以下是一些可能相关的代码（如果需要，我可以发布更多）： 引导孩子进程： /* Call to be traced */ if (ptrace (PTRACE_TRACEME, 0, 0, 0) < 0){ perror ("Proce
