+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

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.
