+\membersection{wxBase64Decode}\label{wxbase64decode}
+
+\func{size\_t}{wxBase64Decode}{\param{void *}{dst}, \param{size\_t }{dstLen},
+\param{const char * }{src}, \param{size\_t }{srcLen = wxNO\_LEN},
+\param{wxBase64DecodeMode }{mode = wxBase64DecodeMode\_Strict},

+
+\func{wxMemoryBuffer}{wxBase64Decode}{\\
+\param{const char * }{src}, \param{size\_t }{srcLen = wxNO\_LEN},\\
+\param{wxBase64DecodeMode }{mode = wxBase64DecodeMode\_Strict},\\
+\param{size\_t }{*posErr = \NULL}}
+
+These function decode a Base64-encoded string. The first version is a raw
+decoding function and decodes the data into the provided buffer \arg{dst} of
+the given size \arg{dstLen}. An error is returned if the buffer is not large
+enough -- that is not at least \helpref{wxBase64DecodedSize(srcLen)}{wxbase64decodedsize}
+bytes. The second version allocates memory internally and returns it as
+\helpref{wxMemoryBuffer}{wxmemorybuffer} and is recommended for normal use.
+
+The first version returns the number of bytes written to the buffer or the
+necessary buffer size if \arg{dst} was \NULL or \texttt{wxCONV\_FAILED} on
+error, e.g. if the output buffer is too small or invalid characters were
+encountered in the input string. The second version returns a buffer with the
+base64 decoded binary equivalent of the input string. In neither case is the
+buffer NUL-terminated.
+
+\wxheading{Parameters}
+
+\docparam{dst}{Pointer to output buffer, may be \NULL to just compute the
+necessary buffer size.}
+
+\docparam{dstLen}{The size of the output buffer, ignored if \arg{dst} is
+\NULL.}
+
+\docparam{src}{The input string, must not be \NULL.}
+
+\docparam{srcLen}{The length of the input string or special value
+\texttt{wxNO\_LEN} if the string is \NUL-terminated and the length should be
+computed by this function itself.}
+
+\docparam{mode}{This parameter specifies the function behaviour when invalid
+characters are encountered in input. By default, any such character stops the
+decoding with error. If the mode is wxBase64DecodeMode\_SkipWS, then the white
+space characters are silently skipped instead. And if it is
+wxBase64DecodeMode\_Relaxed, then all invalid characters are skipped.}
+
+\docparam{posErr}{If this pointer is non-\NULL and an error occurs during
+decoding, it is filled with the index of the invalid character.}

+
+
+\membersection{wxBase64DecodedSize}\label{wxbase64decodedsize}
+
+\func{size\_t}{wxBase64DecodedSize}{\param{size\_t }{srcLen}}
+
+Returns the size of the buffer necessary to contain the data encoded in a
+base64 string of length \arg{srcLen}. This can be useful for allocating a
+buffer to be passed to \helpref{wxBase64Decode}{wxbase64decode}.
+
+
+\membersection{wxBase64Encode}\label{wxbase64encode}
+
+\func{size\_t}{wxBase64Encode}{\param{char *}{dst}, \param{size\_t }{dstLen},
+\param{const void *}{src}, \param{size\_t }{srcLen}}
+
+\func{wxString}{wxBase64Encode}{\param{const void *}{src}, \param{size\_t }{srcLen}}
+
+\func{wxString}{wxBase64Encode}{\param{const wxMemoryBuffer\& }{buf}}
+
+These functions encode the given data using base64. The first of them is the
+raw encoding function writing the output string into provided buffer while the
+other ones return the output as wxString. There is no error return for these
+functions except for the first one which returns \texttt{wxCONV\_FAILED} if the
+output buffer is too small. To allocate the buffer of the correct size, use
+\helpref{wxBase64EncodedSize}{wxbase64encodedsize} or call this function with
+\arg{dst} set to \NULL -- it will then return the necessary buffer size.
+
+\wxheading{Parameters}
+
+\docparam{dst}{The output buffer, may be \NULL to retrieve the needed buffer
+size.}
+
+\docparam{dstLen}{The output buffer size, ignored if \arg{dst} is \NULL.}
+
+\docparam{src}{The input buffer, must not be \NULL.}
+
+\docparam{srcLen}{The length of the input data.}
+
+\wxheading{Include files}
+
+<wx/base64.h>
+
+
+\membersection{wxBase64EncodedSize}\label{wxbase64encodedsize}
+
+\func{size\_t}{wxBase64EncodedSize}{\param{size\_t }{len}}
+
+Returns the length of the string with base64 representation of a buffer of
+specified size \arg{len}. This can be useful for allocating the buffer passed
+to \helpref{wxBase64Encode}{wxbase64encode}.
+
+
\membersection{wxCONCAT}\label{wxconcat}
\func{}{wxCONCAT}{\param{}{x}, \param{}{y}}
+\membersection{wxDEPRECATED}\label{wxdeprecated}
+
+This macro can be used around a function declaration to generate warnings
+indicating that this function is deprecated (i.e. obsolete and planned to be
+removed in the future) when it is used. Only Visual C++ 7 and higher and g++
+compilers currently support this functionality.
+
+Example of use:
+\begin{verbatim}
+ // old function, use wxString version instead
+ wxDEPRECATED( void wxGetSomething(char *buf, size_t len) );
+
+ // ...
+ wxString wxGetSomething();
+\end{verbatim}
+
+
+\membersection{wxDEPRECATED\_BUT\_USED\_INTERNALLY}\label{wxdeprecatedbutusedinternally}
+
+This is a special version of \helpref{wxDEPRECATED}{wxdeprecated} macro which
+only does something when the deprecated function is used from the code outside
+wxWidgets itself but doesn't generate warnings when it is used from wxWidgets.
+It is used with the virtual functions which are called by the library itself --
+even if such function is deprecated the library still has to call it to ensure
+that the existing code overriding it continues to work, but the use of this
+macro ensures that a deprecation warning will be generated if this function is
+used from the user code or, in case of Visual C++, even when it is simply
+overridden.
+
+
\membersection{wxEXPLICIT}\label{wxexplicit}
{\tt wxEXPLICIT} is a macro which expands to the C++ {\tt explicit} keyword if
\membersection{wxON\_BLOCK\_EXIT}\label{wxonblockexit}
\func{}{wxON\_BLOCK\_EXIT0}{\param{}{func}}
+
\func{}{wxON\_BLOCK\_EXIT1}{\param{}{func}, \param{}{p1}}
+
\func{}{wxON\_BLOCK\_EXIT2}{\param{}{func}, \param{}{p1}, \param{}{p2}}
This family of macros allows to ensure that the global function \arg{func}

\func{}{wxON\_BLOCK\_EXIT\_OBJ0}{\param{}{obj}, \param{}{method}}
+
\func{}{wxON\_BLOCK\_EXIT\_OBJ1}{\param{}{obj}, \param{}{method}, \param{}{p1}}
+
\func{}{wxON\_BLOCK\_EXIT\_OBJ2}{\param{}{obj}, \param{}{method}, \param{}{p1}, \param{}{p2}}
This family of macros is similar to \helpref{wxON\_BLOCK\_EXIT}{wxonblockexit}
and current pointer position in screen coordinates.

+
\membersection{::wxGetActiveWindow}\label{wxgetactivewindow}
\func{wxWindow *}{wxGetActiveWindow}{\void}

\texttt{wxBROWSER\_NEW\_WINDOW} flag, a new window is opened for the URL
-(currently this is only supported under Windows).
+(currently this is only supported under Windows). The \arg{url} may also be a
+local file path (with or without \texttt{file://} prefix), if it doesn't
+correspond to an existing file and the URL has no scheme \texttt{http://} is
+prepended to it by default.
Returns \true if the application was successfully launched.

\func{wxLongLong\_t}{wxULL}{\param{}{number}}
\section{Time functions}\label{timefunctions}
-The functions in this section deal with getting the current time and
-starting/stopping the global timers. Please note that the timer functions are
-deprecated because they work with one global timer only and
-\helpref{wxTimer}{wxtimer} and/or \helpref{wxStopWatch}{wxstopwatch} classes
-should be used instead. For retrieving the current time, you may also use
-\helpref{wxDateTime::Now}{wxdatetimenow} or
-\helpref{wxDateTime::UNow}{wxdatetimeunow} methods.

+\section{Atomic operations}\label{atomicoperations}
+
+When using multi-threaded applications, it is often required to access or
+modify memory which is shared between threads. Atomic integer and pointer
+operations are an efficient way to handle this issue (another, less efficient,
+way is to use a \helpref{mutex}{wxmutex} or \helpref{critical
+section}{wxcriticalsection}). A native implementation exists for Windows,
+Linux, Solaris and Mac OS X, for other OS, a
+\helpref{wxCriticalSection}{wxcriticalsection} is used to protect the data.
+
+One particular application is reference counting (used by so-called smart
+pointers).
+
+You should define your variable with the type wxAtomicInt in order to apply
+atomic operations to it.
+
+\wxheading{Include files}
+
+<wx/atomic.h>
+
+\membersection{::wxAtomicInc}\label{wxatomicinc}
+
+\func{void}{wxAtomicInc}{\param{wxAtomicInt\& }{value}}
+
+This function increments \arg{value} in an atomic manner.
+
+
+\membersection{::wxAtomicDec}\label{wxatomicdec}
+
+\func{wxInt32}{wxAtomicDec}{\param{wxAtomicInt\& }{value}}
+
+This function decrements \arg{value} in an atomic manner.
+
+Returns 0 if \arg{value} is 0 after decrementation or any non-zero value (not
+necessarily equal to the value of the variable) otherwise.
