copied!<p>You use handles for stdin, stdout, and stderr. Create process with CreateProcess function to get that handles. Sample code - incomplete for your case, but good example of how to do it:</p> <pre><code>#include <windows.h> #include <stdio.h> #include <tchar.h> /*for test.exe #include <iostream> #include <string> */ void _tmain( int argc, TCHAR *argv[] ) { /*for test.exe std::cout << "test output" << std::endl; for (;;) { std::string line; std::getline(std::cin, line); std::cout << "line: " << line << std::endl; } return;*/ STARTUPINFO si; PROCESS_INFORMATION pi; ZeroMemory( &si, sizeof(si) ); si.cb = sizeof(si); ZeroMemory( &pi, sizeof(pi) ); // Start the child process. if( !CreateProcess( NULL, // No module name (use command line) "test.exe", // Command line NULL, // Process handle not inheritable NULL, // Thread handle not inheritable FALSE, // Set handle inheritance to FALSE 0, // No creation flags NULL, // Use parent's environment block NULL, // Use parent's starting directory &si, // Pointer to STARTUPINFO structure &pi ) // Pointer to PROCESS_INFORMATION structure ) { printf( "CreateProcess failed (%d)\n", GetLastError() ); return; } /* HANDLE hStdInput; HANDLE hStdOutput; HANDLE hStdError;*/ HANDLE me_hStdInput = GetStdHandle(STD_INPUT_HANDLE); HANDLE me_hStdOutput = GetStdHandle(STD_OUTPUT_HANDLE); HANDLE proc_hStdInput = si.hStdInput; HANDLE proc_hStdOutput = si.hStdOutput; char buff[64]; DWORD chars; while (!ReadConsole(me_hStdInput, buff, sizeof(buff), &chars, NULL)) { for (DWORD written = 0, writtenThisTime; written < chars; written += writtenThisTime) if (!WriteConsole(proc_hStdOutput, buff + written, chars - written, &writtenThisTime, NULL)) { //handle error - TODO } } //possibly handle error for ReadConsole - TODO // Wait until child process exits. //WaitForSingleObject( pi.hProcess, INFINITE ); // Close process and thread handles. CloseHandle( pi.hProcess ); CloseHandle( pi.hThread ); } </code></pre>
