HRESULT Read(void* pv,ULONGcb,ULONG* pcbRead);
Parameters
- pv
[in, out] Address of the buffer where the information will be stored. - cb
[in] ULONG value that indicates the size of the buffer. - pcbRead
[out] Address of a ULONG value that indicates the amount of data stored in the buffer.
Return Values
Returns one of the values shown in the following table.
| Value | Description |
|---|---|
| INET_E_DATA_NOT_AVAILABLE | There is no more data available from the server, but more data was expected. |
| INET_E_DOWNLOAD_FAILURE | The read failed. |
| E_PENDING | The read operation is pending. |
| S_OK | The read was successful, but there is still additional data available. |
| S_FALSE | All of the data has been completely downloaded. |
Remarks
Developers who are implementing an asynchronous pluggable protocol must be prepared to have their implementation of IInternetProtocol::Read continue to be called a few extra times after it has returned S_FALSE.
