System::IO::Stream::BeginWrite 方法
Stream::BeginWrite method
发起异步写入操作。
virtual System::SharedPtr<System::IAsyncResult> System::IO::Stream::BeginWrite(System::ArrayPtr<uint8_t> buffer, int offset, int count, System::AsyncCallback callback, System::SharedPtr<System::Object> state)
| 参数 | 类型 | 描述 |
|---|---|---|
| buffer | System::ArrayPtr<uint8_t> | 包含待写入数据的缓冲区 |
| offset | int | 在 buffer 中的 0 基偏移,指示写入数据的起始位置 |
| count | int | 要写入的字节数 |
| 回调 | System::AsyncCallback | 操作完成时要调用的回调函数 |
| state | System::SharedPtr<System::Object> | 用户提供的数据,用于唯一标识每个异步写入操作 |
ReturnValue
一个 IAsyncResult 对象,表示已启动的异步写入操作
