在Linux系统中,我们可以使用`createprocess()`函数来创建新的进程并执行一个不同的程序。`createprocess()`函数实际上是`fork()`和`exec()`函数的组合使用。它首先调用`fork()`函数创建一个新的子进程,然后在子进程中调用`exec()`函数来执行新的程序。 下面是一个简单的示例代码,演示了如何在Linux系统中
在linux上可以使用fork或者clone来进行创建进程 然后使用exec族函数来调用一个外部程序 一个简单的实现大概是这样的 int create_procress(const char *path,const char *name,const char *arg){ pid_t pid; pid=fork(); if(pid == 0) { if(execl(path,name,arg,NULL) == -1...
linux create a process When the system starts up it is running in kernel mode and there is, in a sense, only one process, the initial process. Like all processes, the initial process has a machine state represented by stacks, registers and so on. These will be saved in the initial proc...
然后,在createProcess返回之前,该函数打开进程对象和线程对象,并将每个对象的与进程相关的句柄放入PROCESS_IN FORMATION结构的hProcess和hThread成员中。当CreateProcess在内部打开这些对象时,每个对象的使用计数就变为2。 在系统能够释放进程对象前,该进程必须终止运行(将使用计数递减为1),并且 父进程必须调用CloseHandle(...

父进程能够调用进程创建函数CreateProcess()生成子进程。假设父进程要发送数据到子进程,父进程可调用WriteFile()将数据写入到管道(传递管道写句柄给函数),子进程则调用GetStdHandle()取得管道的读句柄,将该句柄传入ReadFile()后从管道读取数据。 假设是父进程从子进程读取数据,那么由子进程调用GetStdHandle()取得管道...
You have the ability to save snapshots of individual users or snaps, which gives you even more granularity of the process. Finally, you can also script and automate the functionality, so that everything runs in the background, and you are always ready and up-to-date for any data loss eve...
