HttpSendRequestExA function (wininet.h)
Sends the specified request to the HTTP server.
BOOL HttpSendRequestExA( [in] HINTERNET hRequest, [in] LPINTERNET_BUFFERSA lpBuffersIn, [out] LPINTERNET_BUFFERSA lpBuffersOut, [in] DWORD dwFlags, [in] DWORD_PTR dwContext );
A handle returned by a call to the HttpOpenRequest function.
Optional. A pointer to an INTERNET_BUFFERS structure.
Reserved. Must be NULL.
Reserved. Must be zero.
Application-defined context value, if a status callback function has been registered.
If the function succeeds, the function returns TRUE.
If the function fails, it returns FALSE. To get extended error information, call GetLastError.
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.
The wininet.h header defines HttpSendRequestEx as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors.
