<DT><B>Description</B><DD><P>The function returns the time since the 1970-01-01 00:00:00
|
|
measured in seconds. If the pointer <CODE>t</CODE> is not <CODE>NULL</CODE>, the function
|
|
result will also be stored there. If no time is available, <CODE>(time_t)-1</CODE> is
|
|
returned and <CODE>errno</CODE> is set to <CODE>ENOSYS</CODE>.</P>

<DT><B>Limits</B><DD><P>
|
|
<UL>
|
|
<LI>The function is only available as fastcall function, so it may
|
|
only be used in presence of a prototype.</LI>
|
|
<LI>Many platforms supported by cc65 do not have a realtime clock, so the
|
|
returned value may not be valid.</LI>
