其中需要用到几个Windows API :CreatePipe, DuplicateHandle, CreateProcess, ReadFile, WriteFile等,函数详解可参见MSDN. 一、编程实现原理 ( C语言) view plaincopy to clipboard #include <windows.h> //定义句柄: 构成stdin管道的两端句柄 HANDLE hStdInRead; //子进程用的stdin的读入端 HANDLE hStdInWrite; ...
CreatePipe 代码语言:javascript 复制 CreatePipe(_Out_PHANDLEhReadPipe,//该变量接收管道的读取句柄_Out_PHANDLEhWritePipe,// 该变量接收管道的写句柄_In_opt_LPSECURITY_ATTRIBUTESlpPipeAttributes,//安全属性NULL-句柄是否能被子进程继承
当WaitNamedPipe()调用成功后,便可使用CreateFile()将命名管道打开已获得管道的句柄。 然后客户端对命名管道的读写操作利用函数ReadFile()和WriteFile()完成,函数原型如下: BOOL WriteFile( HANDLE hFile, LPCVOID lpBuffer, DWORD nNumberOfBytesToWrite, LPDWORD lpNumberOfBytesWritten, LPOVERLAPPED lpOverlapped )...
You can run multiple commands from a single command line or script using conditional processing symbols. When you run multiple commands with conditional processing symbols, the commands to the right of the conditional processing symbol act based upon the results of the command to the left of the ...

text pane managers (like screen, tmux), etc. Such apps callopenpty()which returns a pair of file descriptors (fd) for the PTY’s master and slave. The app can then fork/exec the child Command-Line application (e.g. bash), which uses its slave fds to listen and return text...
I am writing a batch file script using Windows command-line environment and want to change each occurrence of some text in a file (ex. "FOO") with another (ex. "BAR"). What is the simplest way to do that? Any built in functions?

To use this you just pipe the source command into the program and provide the path of any files you want to duplicate the output to. For example: dir | CopyToFiles files1.txt files2.txt Will display the results of dir as well as store the results in both files1.txt and...
