+
+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. For the version using

+
+\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

+
+\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

+\func{wxString}{wxBase64Encode}{\param{const wxMemoryBuffer\& }{buf}}
+
+These functions encode the given data using base64. The first of them is 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

+compilers currently support this functionality.

+ // ...

+\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.

+
+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.
