wxFileName currently supports the file names in the Unix, DOS/Windows, Mac OS
and VMS formats. Although these formats are quite different, wxFileName tries
-to treat them all in the sam generic way. It supposes that all file names

consist of the following parts: the volume (also known as drive under Windows
or device under VMS), the path which is a sequence of directory names separated
by the \helpref{path separators}{wxfilenamegetpathseparators} and the full
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

+does.

+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

+\func{void}{AssignTempFileName}{\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

+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

+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.
