The rules for determining if the file name is absolute or relative also depends
on the file name format and the only portable way to answer to this question is
to use \helpref{IsAbsolute}{wxfilenameisabsolute} method. To ensure that the
-filename is absolute you may use \helpref{Normalize}{wxfilenamenormalize}.
+filename is absolute you may use \helpref{Normalize}{wxfilenamenormalize}. There
+is also an inverse function \helpref{MakeRelativeTo}{wxfilenamemakerelativeto}
+which undoes what \helpref{Normalize(wxPATH\_NORM\_DOTS}{wxfilenamenormalize}
+does.
Other functions returning information about the file format provided by this
class are \helpref{GetVolumeSeparator}{wxfilenamegetvolumeseparator},\rtfsp
-\helpref{IsPathSeparator}{wxfilenameispathseparator} and\rtfsp
-\helpref{IsWild}{wxfilenameiswild}.
+\helpref{IsPathSeparator}{wxfilenameispathseparator}.

These methods allow to work with the file creation, access and modification
-times:
+times. Note that not all filesystems under all platforms implement these times
+in the same way. For example, the access time under Windows has a resolution of
+one day (so it is really the access date and not time). The access time may be
+updated when the file is executed or not depending on the platform.

\membersection{wxFileName::AssignTempFileName}\label{wxfilenameassigntempfilename}
-\func{void}{AssignTempFileName}{\param{const wxString\& }{prefix}}
+\func{void}{AssignTempFileName}{\param{const wxString\& }{prefix}, \param{wxFile *}{fileTemp = {\tt NULL}}}
The function calls \helpref{CreateTempFileName}{wxfilenamecreatetempfilename} to
create a temporary file and sets this object to the name of the file. If a

-\func{static wxString}{CreateTempFileName}{\param{const wxString\& }{prefix}}
+\func{static wxString}{CreateTempFileName}{\param{const wxString\& }{prefix}, \param{wxFile *}{fileTemp = {\tt NULL}}}
Returns a temporary file name starting with the given {\it prefix}. If
the {\it prefix} is an absolute path, the temporary file is created in this
directory, otherwise it is created in the default system directory for the
temporary files or in the current directory.
-If the function succeeds, the temporary file is actually created (but not
-opened) as well. Under Unix, it will have read and write permissions for the
-owner only.
+If the function succeeds, the temporary file is actually created. If\rtfsp
+{\it fileTemp} is not {\tt NULL}, this file will be opened using the name of
+the temporary file. When possible, this is done in an atomic way ensuring that
+no race condition occurs between the temporary file name generation and opening
+it which could often lead to security compromise on the multiuser systems.
+If {\it fileTemp} is {\tt NULL}, the file is only created, but not opened.
+
+Under Unix, the temporary file will have read and write permissions for the
+owner only to minimize the security problems.

+\docparam{prefix}{Prefix to use for the temporary file name construction}
