InternetWriteFile

BOOL InternetWriteFile(
    IN HINTERNET hFile,
    IN LPCVOID lpBuffer,
    IN DWORD dwNumberOfBytesToWrite,
    OUT LPDWORD lpdwNumberOfBytesWritten
);

Writes data to an open Internet file.

• Returns TRUE if the function succeeds, or FALSE otherwise. To get extended error information, call GetLastError. An application can also use InternetGetLastResponseInfo when necessary.

hFile

Valid handle returned from a previous call to FtpOpenFile or an HINTERNET handle sent by HttpSendRequestEx.

lpBuffer

Address of a buffer that contains the data to be written to the file.

dwNumberOfBytesToWrite

Number of bytes to write to the file.

lpdwNumberOfBytesWritten

Address of a variable that receives the number of bytes written to the buffer. InternetWriteFile sets this value to zero before doing any work or error checking.

When the application is sending data, it must call InternetCloseHandle to end the data transfer.
