   4 \section{\class{wxFileOutputStream}}\label{wxfileoutputstream}
   5
   6 This class represents data written to a file. There are actually
   7 two such groups of classes: this one is based on \helpref{wxFile}{wxfile}
   8 whereas \helpref{wxFFileInputStream}{wxffileinputstream} is based in
   9 the \helpref{wxFFile}{wxffile} 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.

  37
  38 \func{}{wxFileOutputStream}{\param{const wxString\&}{ ofileName}}
  39
  40 Creates a new file with {\it ofilename} name and initializes the stream in
  41 write-only mode.
  42
  43 \func{}{wxFileOutputStream}{\param{wxFile\&}{ file}}
  44
  45 Initializes a file stream in write-only mode using the file I/O object {\it file}.
  46
  47 \func{}{wxFileOutputStream}{\param{int}{ fd}}
  48
  49 Initializes a file stream in write-only mode using the file descriptor {\it fd}.

  57 \membersection{wxFileOutputStream::Ok}
  58
  59 \constfunc{bool}{Ok}{\void}
  60
  61 Returns TRUE if the stream is initialized and ready.
