process.channel


如果 Node.js 进程是由 IPC 通道(参见子进程文档)方式创建的, process.channel 属性保存 IPC 通道的引用。 如果 IPC 通道不存在,则此属性值为 undefined

If the Node.js process was spawned with an IPC channel (see the Child Process documentation), the process.channel property is a reference to the IPC channel. If no IPC channel exists, this property is undefined.
