HttpSendRequestEx function
Sends the specified request to the HTTP server.
Note Callers that need to send extra data beyond what is normally passed to HttpSendRequestEx can do so by calling HttpSendRequest instead.
Syntax
BOOL HttpSendRequestEx( _In_ HINTERNET hRequest, _In_ LPINTERNET_BUFFERS lpBuffersIn, _Out_ LPINTERNET_BUFFERS lpBuffersOut, _In_ DWORD dwFlags, _In_ DWORD_PTR dwContext );
Parameters
- hRequest [in]
-
The handle returned by HttpOpenRequest.
- lpBuffersIn [in]
-
Optional. A pointer to an INTERNET_BUFFERS structure.
- lpBuffersOut [out]
-
Reserved. Must be NULL.
- dwFlags [in]
-
Reserved. Must be zero.
- dwContext [in]
-
Application-defined context value, if a status callback function has been registered.
Return value
If the function succeeds, the function returns TRUE.
If the function fails, it returns FALSE. To get extended error information, call GetLastError.
Remarks
HttpSendRequestEx performs both the send and the receive for the response. This does not allow the application to send any extra data beyond the single buffer that was passed to HttpSendRequestEx. Callers that need to send extra data beyond what is normally passed to HttpSendRequestEx can do so by calling HttpSendRequest instead. After the call to HttpSendRequestEx, send the remaining data by calling InternetWriteFile. Finally, follow up with a call to HttpEndRequest.
Note WinINet does not support server implementations. In addition, it should not be used from a service. For server implementations or services use Microsoft Windows HTTP Services (WinHTTP).
