\section{Thread functions}\label{threadfunctions}
+The functions and macros here mainly exist to make it writing the code which
+may be compiled in multi thread build ({\tt wxUSE\_THREADS} $= 1$) as well as
+in single thread configuration ({\tt wxUSE\_THREADS} $= 0$).
+
+For example, a static variable must be protected against simultaneous access by
+multiple threads in the former configuration but in the latter the extra
+overhead of using the critical section is not needed. To solve this problem,
+the \helpref{wxCRITICAL\_SECTION}{wxcriticalsectionmacro} macro may be used
+to create and use the critical section only when needed.

+\membersection{wxCRIT\_SECT\_DECLARE\_MEMBER}\label{wxcritsectdeclaremember}

+\func{}{wxCRIT\_SECT\_DECLARE}{\param{}{cs}}

+This macro combines \helpref{wxCRIT\_SECT\_DECLARE}{wxcritsectdeclare} and
+\helpref{wxCRIT\_SECT\_LOCKER}{wxcritsectlocker}: it creates a static critical
+section object and also the lock object associated with it. Because of this, it
+can be only used inside a function, not at global scope. For example:
+
+\begin{verbatim}
+int IncCount()
+{
+ static int s_counter = 0;
+
+ wxCRITICAL_SECTION(counter);

+ return ++s_counter;
+}
+\end{verbatim}
+
+(note that we suppose that the function is called the first time from the main

This function returns the translation of string {\it str} in the current
\helpref{locale}{wxlocale}. If the string is not found in any of the loaded
message catalogs (see \helpref{internationalization overview}{internationalization}), the
original string is returned. In debug build, an error message is logged -- this
-should help to find the strings which were not yet translated. As this function
+should help to find the strings which were not yet translated. If
+{\it domain} is specified then only that domain/catalog is searched
+for a matching string. As this function
is used very often, an alternative (and also common in Unix world) syntax is
provided: the \helpref{\_()}{underscore} macro is defined to do the same thing
as wxGetTranslation.
+The second form is used when retrieving translation of string that has
+different singular and plural form in English or different plural forms in some
+other language. It takes two extra arguments: as above, \arg{str}
+parameter must contain the singular form of the string to be converted and
+is used as the key for the search in the catalog. The \arg{strPlural} parameter
+is the plural form (in English). The parameter \arg{n} is used to determine the
+plural form. If no message catalog is found \arg{str} is returned if `n == 1',
+otherwise \arg{strPlural}.
+
+See \urlref{GNU gettext manual}{http://www.gnu.org/manual/gettext/html\_chapter/gettext\_10.html\#SEC150}
+for additional information on plural forms handling. For a shorter alternative
+see the \helpref{wxPLURAL()}{wxplural} macro.
+
+Both versions call \helpref{wxLocale::GetString}{wxlocalegetstring}.
+
+Note that this function is not suitable for literal strings in Unicode
+builds, since the literal strings must be enclosed into
+\helpref{\_T()}{underscoret} or \helpref{wxT}{wxt} macro which makes them
+unrecognised by \texttt{xgettext}, and so they are not extracted to the message
+catalog. Instead, use the \helpref{\_()}{underscore} and

day names already). If you write
+
\begin{verbatim}

...
// use weekdays[n] as usual

// use wxGetTranslation(weekdays[n])

+\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},\\
+\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},

+
+\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.}

+
+\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}}
+
+This macro returns the concatenation of two tokens \arg{x} and \arg{y}.
+
+
+\membersection{wxDYNLIB\_FUNCTION}\label{wxdynlibfunction}
+
+\func{}{wxDYNLIB\_FUNCTION}{\param{}{type}, \param{}{name}, \param{}{dynlib}}
+
+When loading a function from a DLL you always have to cast the returned
+{\tt void *} pointer to the correct type and, even more annoyingly, you have to
+repeat this type twice if you want to declare and define a function pointer all
+in one line
+
+This macro makes this slightly less painful by allowing you to specify the
+type only once, as the first parameter, and creating a variable of this type
+named after the function but with {\tt pfn} prefix and initialized with the
+function \arg{name} from the \helpref{wxDynamicLibrary}{wxdynamiclibrary}
+\arg{dynlib}.
+
+\wxheading{Parameters}
+
+\docparam{type}{the type of the function}
+
+\docparam{name}{the name of the function to load, not a string (without quotes,
+it is quoted automatically by the macro)}
+
+\docparam{dynlib}{the library to load the function from}
+
+
+
+\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
code which might have to be compiled with an old compiler without support for
this language feature but still take advantage of it when it is available.
+
+
+\membersection{::wxGetKeyState}\label{wxgetkeystate}
+
+\func{bool}{wxGetKeyState}{\param{wxKeyCode }{key}}
+
+For normal keys, returns \true if the specified key is currently down.
+
+For togglable keys (Caps Lock, Num Lock and Scroll Lock), returns
+\true if the key is toggled such that its LED indicator is lit. There is
+currently no way to test whether togglable keys are up or down.
+
+Even though there are virtual key codes defined for mouse buttons, they
+cannot be used with this function currently.

This function is called whenever one of debugging macros fails (i.e. condition
is false in an assertion). It is only defined in the debug mode, in release
To override the default behaviour in the debug builds which is to show the user
a dialog asking whether he wants to abort the program, continue or continue
ignoring any subsequent assert failures, you may override
-\helpref{wxApp::OnAssert}{wxapponassert} which is called by this function if
+\helpref{wxApp::OnAssertFailure}{wxapponassertfailure} which is called by this function if
the global application object exists.

+\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.

+Returns 0 if \arg{value} is 0 after decrementation or any non-zero value (not
+necessarily equal to the value of the variable) otherwise.
