\section{\class{wxString}}\label{wxstring}
wxString is a class representing a character string. Please see the
-\helpref{wxString overview}{wxstringoverview} for more information about it. As explained
-there, wxString implements about 90\% of methods of the std::string class (iterators
-are not supported, nor all methods which use them).
-These standard functions are not documented in this manual so please see the STL documentation.
+\helpref{wxString overview}{wxstringoverview} for more information about it.
+
+As explained there, wxString implements most of the methods of the std::string
+class.
+These standard functions are not documented in this manual, please see the
+\urlref{STL documentation}{http://www.cppreference.com/cppstl.html}).
The behaviour of all these functions is identical to the behaviour described
there.
+You may notice that wxString sometimes has many functions which do the same
+thing like, for example, \helpref{Length()}{wxstringlength},
+\helpref{Len()}{wxstringlen} and {\tt length()} which all return the string
+length. In all cases of such duplication the {\tt std::string}-compatible
+method ({\tt length()} in this case, always the lowercase version) should be
+used as it will ensure smoother transition to {\tt std::string} when wxWidgets
+starts using it instead of wxString.

+A string may be constructed either from a C string, (some number of copies of)
a single character or a wide (UNICODE) string. For all constructors (except the
default which creates an empty string) there is also a corresponding assignment
operator.

or empty it.

-\membersection{Character access}

+\membersection{Character access}\label{characteraccessinwxstring}
Many functions in this section take a character index in the string. As with C
strings and/or arrays, the indices start from $0$, so the first character of a
string is string[$0$]. Attempt to access a character beyond the end of the
-string (which may be even $0$ if the string is empty) will provocate an assert

+\membersection{Concatenation}\label{concatenationinwxstring}
Anything may be concatenated (appended to) with a string. However, you can't
append something to a C string (including literal constants), so to do this it

\helpref{Prepend}{wxstringprepend}
-\membersection{Comparison}
+
+\membersection{Comparison}\label{comparisoninwxstring}
The default comparison function \helpref{Cmp}{wxstringcmp} is case-sensitive and
so is the default version of \helpref{IsSameAs}{wxstringissameas}. For case
insensitive comparisons you should use \helpref{CmpNoCase}{wxstringcmpnocase} or
give a second parameter to IsSameAs. This last function is may be more
convenient if only equality of the strings matters because it returns a boolean
-true value if the strings are the same and not 0 (which is usually FALSE in C)
-as Cmp does.
+\true value if the strings are the same and not 0 (which is usually false in C)
+as {\tt Cmp()} does.
\helpref{Matches}{wxstringmatches} is a poor man's regular expression matcher:
it only understands '*' and '?' metacharacters in the sense of DOS command line
interpreter.
+\helpref{StartsWith}{wxstringstartswith} is helpful when parsing a line of
+text which should start with some predefined prefix and is more efficient than
+doing direct string comparison as you would also have to precalculate the
+length of the prefix then.

+
+The value of {\it base} must be comprised between $2$ and $36$, inclusive, or

+\membersection{wxStringBufferLength::wxStringBufferLength}\label{wxstringbufferlengthctor}
+
+\func{}{wxStringBufferLength}{\param{const wxString\& }{str}, \param{size\_t }{len}}
+
+Constructs a writable string buffer object associated with the given string
+and containing enough space for at least {\it len} characters. Basically, this
+is equivalent to calling \helpref{GetWriteBuf}{wxstringgetwritebuf} and
+saving the result.
+
+
+\membersection{wxStringBufferLength::\destruct{wxStringBufferLength}}\label{wxstringbufferlengthdtor}
+
+\func{}{\destruct{wxStringBufferLength}}{\void}
+
+Restores the string passed to the constructor to the usable state by calling
+\helpref{UngetWriteBuf}{wxstringungetwritebuf} on it.
+
+
+\membersection{wxStringBufferLength::SetLength}\label{wxstringbufferlengthsetlength}
+
+\func{void}{SetLength}{\param{size\_t }{nLength}}
+
+Sets the internal length of the string referred to by wxStringBufferLength to
+{\it nLength} characters.
+
+Must be called before wxStringBufferLength destructs.
+
+
+\membersection{wxStringBufferLength::operator wxChar *}\label{wxstringbufferlengthwxchar}
+
+\func{wxChar *}{operator wxChar *}{\void}
+
+Returns the writable pointer to a buffer of the size at least equal to the
+length specified in the constructor.
