.SH NAME
wxTempFileOutputStream \- 
  Stream to safely replace an existing file
 
.SH DESCRIPTION

  


   wxTempFileOutputStream is an output stream based on
   wxTempFile
   . It provides a relatively safe way to replace the contents of the existing
   file.

.SS  wxTempFileOutputStream (const wxString& fileName)

     


      Associates wxTempFileOutputStream with the file to be replaced and opens
      it. You should use
      IsOk
      to verify if the constructor succeeded.
     
     


      Call
      Commit()
      or
      Close()
      to replace the old file and close this one. Calling
      Discard()
      (or allowing the destructor to do it) will discard the changes.
     
    
   
  
.SS bool Commit ()

     


      Validate changes: deletes the old file of the given name and renames the
      new file to the old name. Returns
      true
      if both actions succeeded. If
      false
      is returned it may unfortunately mean two quite different things: either
      that either the old file couldn't be deleted or that the new file couldn't
      be renamed to the old name.
     
    
   
  
.SS void Discard ()

     


      Discard changes: the old file contents are not changed, the temporary file
      is deleted.
