## SslStream::BeginWrite method


Initiates an asynchronous write operation.

```cpp
System::SharedPtr<IAsyncResult> System::Net::Security::SslStream::BeginWrite(System::ArrayPtr<uint8_t> buffer, int32_t offset, int32_t count, AsyncCallback asyncCallback, System::SharedPtr<Object> asyncState) override
```


| Parameter | Type | Description |
| --- | --- | --- |
| buffer | System::ArrayPtr\<uint8_t\> | The byte array to write data to. |
| offset | int32_t | The offset in bytes in the specified array. |
| count | int32_t | The number of bytes to write. |
| asyncCallback | AsyncCallback | A callback to be called when the operation completes. |
| asyncState | System::SharedPtr\<Object\> | User-provided data used to uniquely identify each asynchronous write operation. |

### ReturnValue

An [IAsyncResult](../../../system/iasyncresult/) object representing the initiated asynchronous write operation.
