process.channel


如果 Node.js 进程是使用 IPC 通道生成的(请参阅 子进程 文档),则 process.channel 属性是对 IPC 通道的引用。如果不存在 IPC 通道,则此属性为 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.
