wxBufferedOutputStream

This stream acts as a cache. It caches the bytes to be written to the specified output stream (See wxFilterOutputStream). The data is only written when the cache is full, when the buffered stream is destroyed or when calling SeekO().

This class may not be used without some other stream to write the data to (such as a file stream or a memory stream).
