   1 \section{\class{wxFileInputStream}}\label{wxfileinputstream}
   2
   3 This class represents data read in from a file. There are actually
   4 two such groups of classes: this one is based on \helpref{wxFile}{wxfile}
   5 whereas \helpref{wxFFileInputStream}{wxffileinputstream} is based in
   6 the \helpref{wxFFile}{wxffile} class.
   7
   8 Note that \helpref{SeekI()}{wxinputstreamseeki}
   9 can seek beyond the end of the stream (file) and will thus not return
  10 {\it wxInvalidOffset} for that.
