+\func{bool}{wxGetResource}{\param{const wxString\& }{section}, \param{const wxString\& }{entry},

+
+Gets a resource value from the resource database (for example, WIN.INI, or
+.Xdefaults). If {\it file} is NULL, WIN.INI or .Xdefaults is used,
+otherwise the specified file is used.
+
+Under X, if an application class (wxApp::GetClassName) has been defined,
+it is appended to the string /usr/lib/X11/app-defaults/ to try to find
+an applications default file when merging all resource databases.
+
+The reason for passing the result in an argument is that it
+can be convenient to define a default value, which gets overridden
+if the value exists in the resource file. It saves a separate
+test for that resource's existence, and it also allows
+the overloading of the function for different types.

+\membersection{::wxLoadUserResource}\label{wxloaduserresource}
+
+\func{wxString}{wxLoadUserResource}{\param{const wxString\& }{resourceName}, \param{const wxString\& }{resourceType=``TEXT"}}
+
+Loads a user-defined Windows resource as a string. If the resource is found, the function creates
+a new character array and copies the data into it. A pointer to this data is returned. If unsuccessful, NULL is returned.
+
+The resource must be defined in the {\tt .rc} file using the following syntax:
+
+\begin{verbatim}
+myResource TEXT file.ext
+\end{verbatim}
+
+where {\tt file.ext} is a file that the resource compiler can find.
+
+One use of this is to store {\tt .wxr} files instead of including the data in the C++ file; some compilers
+cannot cope with the long strings in a {\tt .wxr} file. The resource data can then be parsed
+using \helpref{wxResourceParseString}{wxresourceparsestring}.

+Tells the system to delete the specified object when

+\membersection{::wxPostEvent}\label{wxpostevent}
+
+\func{void}{wxPostEvent}{\param{wxEvtHandler *}{dest}, \param{wxEvent\& }{event}}
+
+This function posts the event to the specified {\it dest} object. The
+difference between sending an event and posting it is that in the first case
+the event is processed before the function returns (in wxWindows, event sending
+is done with \helpref{ProcessEvent}{wxevthandlerprocessevent} function), but in
+the second, the function returns immediately and the event will be processed
+sometime later - usually during the next even loop iteration.
+
+Note that a copy of the {\it event} is made by the function, so the original
+copy can be deleted as soon as function returns. This function can also be used
+to send events between different threads safely. As this function makes a
+copy of the event, the event needs to have a fully implemented Clone() method,
+which may not be the case for all event in wxWindows.

+Strips any menu codes from {\it in} and places the result

+
+Writes a resource value into the resource database (for example, WIN.INI, or
+.Xdefaults). If {\it file} is NULL, WIN.INI or .Xdefaults is used,
+otherwise the specified file is used.
+
+Under X, the resource databases are cached until the internal function
+\rtfsp{\bf wxFlushResources} is called automatically on exit, when
+all updated resource databases are written to their files.
+
+Note that it is considered bad manners to write to the .Xdefaults
+file under Unix, although the WIN.INI file is fair game under Windows.

+\section{Byte order macros}\label{macros}
+
+The endian-ness issues (that is the difference between big-endian and
+little-endian architectures) are important for the portable programs working
+with the external binary data (for example, data files or data coming from
+network) which is usually in some fixed, platform-independent format. The
+macros are helpful for transforming the data to the correct format.

+
+This macro will swap the bytes of the {\it value} variable from little
+endian to big endian or vice versa if the program is compiled on a
+big-endian architecture (such as Sun work stations). If the program has
+been compiled on a little-endian architecture, the value will be unchanged.
+
+Use these macros to read data from and write data to a file that stores

+Use these macros to read data from and write data to a file that stores

+\section{RTTI functions}\label{macros}
+
+wxWindows uses its own RTTI ("run-time type identification") system which
+predates the current standard C++ RTTI and so is kept for backwards
+compatribility reasons but also because it allows some things which the
+standard RTTI doesn't directly support (such as creating a class from its
+name).
+
+The standard C++ RTTI can be used in the user code without any problems and in
+general you shouldn't need to use the functions and the macros in this section
+unless you are thinking of modifying or adding any wxWindows classes.
