\section{\class{wxFileInputStream}}\label{wxfileinputstream}
+This classes represent data streams to and from a file. There are actually
+two such groups of classes: those documented here, and another group called
+wxFFileInputStream, wxFFileOutputStream and wxFFileStream which are not
+based on file descriptors (and their wxWindows equivalent wxFile) but the
+FILE* type (and wxFFile). Apart from the different constructor ("FILE *file"
+instead if "int fd") their interface is identical.
+
\wxheading{Derived from}
\helpref{wxInputStream}{wxinputstream}
This class provides functions that write text datas using an output stream.
So, you can write \it{text} floats, integers.
-For example:
+You can also simulate the C++ cout class:
\begin{verbatim}
- wxFileOutputStream output( "mytext.txt" );
- wxTextOutputStream text( output );
+ wxFFileOutputStream output( stderr );
+ wxTextOutputStream cout( output );
- output << "This is a text line" << endl;
- output << 1234;
- output << 1.23456;
+ cout << "This is a text line" << endl;
+ cout << 1234;
+ cout << 1.23456;
\end{verbatim}
The wxTextOutputStream writes text files (or streams) on DOS, Macintosh
