Returns a pointer to the string data ({\tt const char*} in ANSI build,

+\constfunc{int}{Cmp}{\param{const wxString\&}{ s}}

\constfunc{int}{CmpNoCase}{\param{const char*}{ psz}}
Case-insensitive comparison.
Returns string representation suitable for passing to OS' functions for
file handling. In ANSI build, this is same as \helpref{c\_str}{wxstringcstr}.
In Unicode build, returned value can be either wide character string

This static function returns the string containing the result of calling
\helpref{PrintfV}{wxstringprintfv} with the passed parameters on it.
\membersection{wxString::GetData}\label{wxstringgetdata}
-\constfunc{const char*}{GetData}{\void}
+\constfunc{const wxChar*}{GetData}{\void}
wxWidgets compatibility conversion. Returns a constant pointer to the data in the string.
Same as \helpref{wxString::Find}{wxstringfind}.
-\constfunc{size\_t}{Index}{\param{const char*}{ sz}, \param{bool}{ caseSensitive = true}, \param{bool}{ fromEnd = false}}
-
-Search the element in the array, starting from either side.

-If {\it fromEnd} is true, reverse search direction.
-
-If {\bf caseSensitive}, comparison is case sensitive (the default).
-
-Returns the index of the first item matched, or {\tt wxNOT\_FOUND}.

%\membersection{wxString::insert}\label{wxstringinsert}
% Wrong!
Similar to the standard function {\it sprintf()}. Returns the number of
characters written, or an integer less than zero on error.
+Note that if {\tt wxUSE\_PRINTF\_POS\_PARAMS} is set to 1, then this function supports
+Unix98-style positional parameters:
+
+\begin{verbatim}
+ wxString str;
+
+ str.Printf(wxT("%d %d %d"), 1, 2, 3);
+ // str now contains "1 2 3"
+
+ str.Printf(wxT("%2$d %3$d %1$d"), 1, 2, 3);
+ // str now contains "2 3 1"
+\end{verbatim}
+
{\bf NB:} This function will use a safe version of {\it vsprintf()} (usually called
{\it vsnprintf()}) whenever available to always allocate the buffer of correct
size. Unfortunately, this function is not available on all platforms and the

+\membersection{wxString::EndsWith}\label{wxstringendswith}
+
+\constfunc{bool}{EndsWith}{\param{const wxChar }{*suffix}, \param{wxString }{*rest = NULL}}
+
+This function can be used to test if the string ends with the specified
+{\it suffix}. If it does, the function will return {\tt true} and put the
+beginning of the string before the suffix into {\it rest} string if it is not
+{\tt NULL}. Otherwise, the function returns {\tt false} and doesn't

Returns {\tt true} on success in which case the number is stored in the

+represent a valid number in the given base. Please notice that this function
+behaves in the same way as the standard \texttt{strtoul()} and so it simply
+converts negative numbers to unsigned representation instead of rejecting them
+(e.g. $-1$ is returned as \texttt{ULONG\_MAX}).
See \helpref{wxString::ToLong}{wxstringtolong} for the more detailed
description of the {\it base} parameter.
\func{wxString\&}{Trim}{\param{bool}{ fromRight = true}}
-Removes spaces from the left or from the right (default).
+Removes white-space (space, tabs, form feed, newline and carriage return) from
