+ * TclpOpenTemporaryFile, TclUnixOpenTemporaryFile --
+ *
+ * Creates a temporary file, possibly based on the supplied bits and
+ * pieces of template supplied in the first three arguments. If the
+ * fourth argument is non-NULL, it contains a Tcl_Obj to store the name
+ * of the temporary file in (and it is caller's responsibility to clean
+ * up). If the fourth argument is NULL, try to arrange for the temporary
+ * file to go away once it is no longer needed.
+ *
+ * Results:
+ * A read-write Tcl Channel open on the file for TclpOpenTemporaryFile,
+ * or a file descriptor (or -1 on failure) for TclUnixOpenTemporaryFile.
+ *
+ * Side effects:
+ * Accesses the filesystem. Will set the contents of the Tcl_Obj fourth
+ * argument (if that is non-NULL).
