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

-
-get a temp file name starting with thespecified 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
+temporary file couldn't be created, the object is put into the\rtfsp
+\helpref{invalid}{wxfilenameisok} state.

+\func{static wxString}{CreateTempFileName}{\param{const wxString\& }{prefix}, \param{wxFile *}{fileTemp = {\tt NULL}}}
-\func{bool}{DirExists}{\void}
+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. 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.
+
+\wxheading{Parameters}
+
+\docparam{prefix}{Prefix to use for the temporary file name construction}
-does the directory with this name exists?
+\docparam{fileTemp}{The file to open or {\tt NULL} to just get the name}
+\wxheading{Return value}
+
+The full temporary file name or an empty string on error.

\constfunc{bool}{IsOk}{\void}
-file tests
-is the filename valid at all?
-
+Returns {\tt TRUE} if the filename is valid, {\tt FALSE} if it is not
+initialized yet. The assignment functions and
+\helpref{Clear}{wxfilenameclear} may reset the object to the uninitialized,
+invalid state (the former only do it on failure).
\membersection{wxFileName::IsPathSeparator}\label{wxfilenameispathseparator}
\func{bool}{IsPathSeparator}{\param{wxChar }{ch}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
-is the char a path separator for this format?
-
+Returns {\tt TRUE} if the char is a path separator for this format.
\membersection{wxFileName::IsRelative}\label{wxfilenameisrelative}
\func{bool}{IsRelative}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}
-is this filename relative?
-
+Returns {\tt TRUE} if this filename is not absolute.
\membersection{wxFileName::IsWild}\label{wxfilenameiswild}
FIXME: what exactly does this do?
+\membersection{wxFileName::MakeRelativeTo}\label{wxfilenamemakerelativeto}
+
+\func{bool}{MakeRelativeTo}{\param{const wxString\& }{pathBase = ""}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
+
+This function tries to put this file name in a form relative to {\it pathBase}.
+In other words, it returns the file name which should be used to access this
+file if the current directory were {\it pathBase}.
+
+\docparam{pathBase}{the directory to use as root, current directory is used by
+default}
+
+\docparam{format}{the file name format, native by default}
+
+\wxheading{Return value}
+
+{\tt TRUE} if the file name has been changed, {\tt FALSE} if we failed to do
+anything with it (currently this only happens if the file name is on a volume
+different from the volume specified by {\it pathBase}).
