\section{\class{wxFileInputStream}}\label{wxfileinputstream}
This class represents data read in from a file. There are actually
two such groups of classes: this one is based on \helpref{wxFile}{wxfile}
whereas \helpref{wxFFileInputStream}{wxffileinputstream} is based in
the \helpref{wxFFile}{wxffile} class.
Note that \helpref{wxFile}{wxfile} and \helpref{wxFFile}{wxffile} differ
in one aspect, namely when to report that the end of the file has been
reached. This is documented in \helpref{wxFile::Eof}{wxfileeof} and
\helpref{wxFFile::Eof}{wxffileeof} and the behaviour of the stream
classes reflects this difference, i.e. wxFileInputStream will report
wxSTREAM\_EOF after having read the last byte whereas wxFFileInputStream
will report wxSTREAM\_EOF after trying to read {\it past} the last byte.
