服務端

// 規定創建命名管道的程序是服務端 // 本程序服務端負責接收數據并打印 #include <stdio.h> #include <Windows.h>BOOL Server() {char szBuffer[0x100] = { 0 };DWORD dwRead = 0;// 創建雙向管道HANDLE hPipe = CreateNamedPipeA("\\\\.\\pipe\\hambaga", PIPE_ACCESS_DUPLEX, PIPE_TYPE_BYTE | PIPE_READMODE_BYTE,1, 0, 0, 1000, NULL);if (INVALID_HANDLE_VALUE == hPipe){printf("創建命名管道失敗\n");CloseHandle(hPipe);return -1;}printf("創建命名管道成功，等待客戶端連接...\n");if (ConnectNamedPipe(hPipe, NULL) == FALSE){printf("與客戶機連接失敗\n");CloseHandle(hPipe);return -1;}while (1){printf("正在等待數據: ");if (ReadFile(hPipe, szBuffer, 0x100, &dwRead, NULL) == FALSE){printf("讀取數據失敗\n");break;}szBuffer[dwRead] = 0;printf("%s\n", szBuffer);}CloseHandle(hPipe);return TRUE; }int main() {Server();return 0; }

客戶端

#define _CRT_SECURE_NO_WARNINGS #include <Windows.h> #include <stdio.h>BOOL Client() {char szBuffer[0x100] = { 0 };DWORD dwWrite = 0;if (WaitNamedPipeA("\\\\.\\pipe\\hambaga", NMPWAIT_WAIT_FOREVER) == FALSE){printf("等待命名管道實例失敗\n");return FALSE;}HANDLE hPipe = CreateFileA("\\\\.\\pipe\\hambaga", GENERIC_READ | GENERIC_WRITE, 0,NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);if (hPipe == INVALID_HANDLE_VALUE){printf("創建命名管道失敗\n");CloseHandle(hPipe);return FALSE;}printf("連接服務器成功\n");while (1){scanf("%s", szBuffer);if (FALSE == WriteFile(hPipe, szBuffer, strlen(szBuffer), &dwWrite, NULL)){printf("寫入管道失敗\n");break;}}CloseHandle(hPipe);return TRUE; }int main() {Client();system("pause");return 0; }
