+
+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.}

+\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}.
