我主要取得文件描述符

Linux/Unix下:

pipe(pipeline);
write(pipeline[1], data_source, data_source_len);
pipeline[0] <- 取得文件描述符

windows下我用CreatePipe咋都实现不了
感觉linux下pipe非阻塞的
windows下CreatePipe后WriteFile后就阻塞住了
查资料要创建进程, 可是捣鼓一通也不行是否能像下面这样不创建进程?

HANDLE piperead, pipewrite;
SECURITY_ATTRIBUTES sa;

sa.nLength = sizeof(SECURITY_ATTRIBUTES);
sa.lpSecurityDescriptor = NULL;
sa.bInheritHandle = TRUE;
if (!CreatePipe(&piperead, &pipewrite, &sa, 0)) {
    return NULL;
}

if (!WriteFile(pipewrite, data_source, data_source_len, NULL, NULL)) {
    return NULL;
}
int file_des = _open_osfhandle((zend_intptr_t)piperead, 0); <- 取得文件描述符

感谢回复, 查了下匿名管道不支持异步.
退而求其次, 我查了下命名管道的用法, 写出来后不阻塞, 但数据不对,是否我取文件描述符取的不对?

    const char *pStrPipeName = "\\\\.\\pipe\\NamePipe_MoreWindows";
    DWORD dwLen = 0;
    OVERLAPPED ov;
    memset(&ov, 0, sizeof(OVERLAPPED));

    HANDLE hPipe = CreateNamedPipe(pStrPipeName, PIPE_ACCESS_DUPLEX, PIPE_TYPE_BYTE | PIPE_READMODE_BYTE | PIPE_NOWAIT, PIPE_UNLIMITED_INSTANCES, 0, 0, NMPWAIT_WAIT_FOREVER, 0);
    if (WaitNamedPipe(pStrPipeName, NMPWAIT_WAIT_FOREVER) == FALSE) {
        return NULL;
    }

    WriteFileEx(hPipe, data_source, data_source_len, &dwLen, &ov);

    int file_des = _open_osfhandle((intptr_t)hPipe, 0);

已经对照msdn手册学会用了,多谢大家...
