<p><strong>Description</strong><br>
|
||
|
|
<code>time</code> looks up the best available representation of the current
|
||
|
|
time and returns it, encoded as a <code>time_t</code>. It stores the same
|
||
|
|
value at <var>t</var> unless the argument is <code>NULL</code>.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
A <code>-1</code> result means the current time is not available; otherwise the
|
||
|
|
result represents the current time.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Portability</strong><br>
|
||
|
|
ANSI C requires <code>time</code>.
|
||
|
|
</p>
|
||
|
|
<p>Supporting OS subroutine required: Some implementations require
|
||
|
|
<code>gettimeofday</code>.
