The Send method sends a buffer asynchronously. It performs an overlapped send operation.

Syntax

HRESULT Send(
  [in]  IFWXIOBuffer* pIOBuffer,
  [in]  IFWXIOCompletion* pIFWXIOCompletion,
  [in]  UserContextType UserData
);

Parameters

pIOBuffer
Pointer to the buffer to send.
pIFWXIOCompletion
Pointer to the IFWXIOCompletion interface that is notified when the send operation is completed. Set this parameter to NULL if notification is not required.
UserData
An opaque value to pass to the IFWXIOCompletion::CompleteAsyncIO notification method. This parameter provides a context to the notification, thereby allowing identification of each send operation.

Return Value

This method returns S_OK if the call is successful; otherwise, it returns an error code.

Remarks

To receive a notification when the send operation is completed, specify an IFWXIOCompletion interface pointer in the pIFWXIOCompletion parameter.
