forking() and CreateProcess()

由 穿精又带淫゛_ 提交于 2019-12-09 16:45:34
问题 Are forking() and CreateProcess(with all required arguments), the same thing for Linux and WinXP, respectively? If they are different, then could someone explain the difference in terms of what happens in each of the two cases? Thanks 回答1: They do different things, and on different systems. CreateProcess is a Windows-only function, while fork is only on POSIX (e.g. Linux and Mac OSX) systems. The fork system call creates a new process and continue execution in both the parent and the child

问题 I have an NT service that calls a console program written in Delphi 7, let's call it failover.exe that in turn calls NETSH using a procedure I found: procedure ExecConsoleApp(CommandLine: ansistring; Output, Errors: TStringList); Note: ExecConsoleApp uses CreateProcess, see the following link for full code: http://www.delphisources.ru/pages/faq/base/createprocess_console.html I would pass the following to CommandLine before calling ExecConsoleApp : cmd.exe /c "C:\Windows\system32\netsh.exe

AppCertDlls: Process creation slowdown on Win32 caused by virus

I've been enjoying a hefty process creation penalty on my Windows XP Home SP3 for about two months. The problem is most manifest and annoying with tasks that do create lots of processes, such as shell scripts (incidentally, bash scripts on Cygwin), Makefiles, or unpacking an IzPack package such as the SpringSource Tool Suite installer (lots of separate unpack200.exe JAR extractor processes). I'm sure it's process creation from observing bash script diagnostic output, or watching processes appear in task manager. There is no noticeable delay once a process is up and running. I've reported that

CreateProcessWithLogonW() problems - Need to launch sub-processes with the same user

由 心不动则不痛 提交于 2019-12-08 05:34:35
问题 I have a Windows executable that is launched from within a service by calling CreateProcessWithLogonW() with a set of specfied user details. This works fine and the process starts as expected. However, when this process tries to launch other processes itself, currently just using CreateProcess() these start then die straight away - they are executables that require desktop access. After reading up on Microsoft's article on CreateProcess() - http://msdn.microsoft.com/en-us/library/ms682425(VS

原因，是SVN使用了命令行工具，如果本地没有SVN的命令行工具，则导致出错。 解决办法： 1、安装客户端 http://ncu.dl.sourceforge.net/project/tortoisesvn/1.8.7/Application/TortoiseSVN-1.8.7.25475-x64-svn-1.8.9.msi http://jaist.dl.sourceforge.net/project/tortoisesvn/1.8.7/Language%20Packs/LanguagePack_1.8.7.25475-x64-zh_CN.msi 注意：安装时候必须选中command line 。。。这个选项。 2、完成后配置IDEA 解决问题 来源： oschina 链接： https://my.oschina.net/u/779083/blog/283220
