   4 \section{\class{wxFFileInputStream}}\label{wxffileinputstream}
   5
   6 This class represents data read in from a file. There are actually
   7 two such groups of classes: this one is based on \helpref{wxFFile}{wxffile}
   8 whereas \helpref{wxFileInputStream}{wxfileinputstream} is based in
   9 the \helpref{wxFile}{wxfile} class.
  10
  11 Note that \helpref{wxFile}{wxfile} and \helpref{wxFFile}{wxffile} differ
  12 in one aspect, namely when to report that the end of the file has been
  13 reached. This is documented in \helpref{wxFile::Eof}{wxfileeof} and
  14 \helpref{wxFFile::Eof}{wxffileeof} and the behaviour of the stream
  15 classes reflects this difference, i.e. wxFileInputStream will report
  16 wxSTREAM\_EOF after having read the last byte whereas wxFFileInputStream
  17 will report wxSTREAM\_EOF after trying to read {\it past} the last byte.
