+{\it flags} can be one or more of the following bit values ored together:
+
+\begin{verbatim}
+// Open Bit Flags
+enum {
+ wxFS_READ = 1, // Open for reading
+ wxFS_SEEKABLE = 4 // Returned stream will be seekable
+};
+\end{verbatim}
+
+A stream opened with just the default {\it wxFS\_READ} flag may
+or may not be seekable depending on the underlying source.
+Passing {\it wxFS\_READ | wxFS\_SEEKABLE} for {\it flags} will
+back a stream that is not natively seekable with memory or a file
+and return a stream that is always seekable.
