<p>"How long does my C++ code take to run?"<p>The Boost Timer library
|
||
answers that question and does so portably, with as little as one #include and one
|
||
additional line of code.<p>The Boost Timer library has two distinct sets of
|
||
components:<ul>
|
||
<li>If you are new to the library, please go directly to the version 2
|
||
<a href="cpu_timers.html">CPU timers</a> page.</li>
|
||
<li>If you are interested in
|
||
the original library, now deprecated, read on below.</li>
|
||
</ul>
|
||
<h2>
|
||
<a href="cpu_timers.html">CPU timers</a></h2>
|
||
<p>These version 2 components conform to current Boost practice:</p>
|
||
<ul>
|
||
<li>The interfaces and their semantics are the same across all platforms.</li>
|
||
<li>The internal implementation uses operating system specific APIs to achieve
|
||
higher precision and supply functionality not otherwise available. </li>
|
||
<li>The headers live in a sub-directory, <code><boost/timer/...></code>.</li>
|
||
<li>The content is in a sub-namespace, <code>boost::timer</code>.</li>
|
||
</ul>
|
||
<h2 dir="ltr">
|
||
<a href="original_timer.html">Original timers</a></h2>
|
||
<p>These version 1 components are deprecated. They date from the earliest days
|
||
of Boost and do not conform to current Boost practice:</p>
|
||
<ul>
|
||
<li>The interfaces are the same across all platforms, but the semantics differ
|
||
according to platform. Wall-clock time is measured on Windows, while CPU time
|
||
is measured on POSIX-like systems.</li>
|
||
<li>The internal implementation uses only C/C++ standard library functions, so
|
||
cannot supply desirable precision and functionality.</li>
|
||
<li>The headers live in the main Boost header directory.</li>
|
||
<li>The content are in namespace <code>boost</code>.</li>
|
||
</ul>
