  <a name="1204862"> </a><font size=2  face="Verdana, Arial, Helvetica, sans-serif">As well as all the "user visible" OS20 functions, there is a hidden function which is used by the <font size=2 face=Courier><strong>TIMEOUT_IMMEDIATE</strong></font> and <font size=2 face=Courier><strong>TIMEOUT_INFINITY</strong></font> macros. This is <font size=2 face=Courier><strong>time_pointers()</strong></font>, which is used to ensure that the same values are used for these pointers in all code units. This function must also be imported by any RCUs which use these macros:</font>
