On Windows, the integer is of type long and this class is implemented using InterlockedIncrement and InterlockedDecrement integer is of type long. On Unix systems with GNU std++ support for EXCHANGE_AND_ADD, the integer is of type _Atomic_word (normally int) On all other systems, this class is implemented using <a class="el" href="classPCriticalSection.html">PCriticalSection</a> and the integer is of type int. <p><hr><h2>Constructor & Destructor Documentation</h2><a name="a0" doxytag="PAtomicInteger::PAtomicInteger"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> PAtomicInteger::PAtomicInteger </td> <td class="md" valign="top">( </td> <td class="md" nowrap valign="top">long </td> <td class="mdname1" valign="top" nowrap> <em>v</em> = 0 </td> <td class="md" valign="top">) </td> <td class="md" nowrap><code> [inline]</code></td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>Create a PAtomicInteger with the specified initial value </td> </tr></table><hr><h2>Member Function Documentation</h2><a name="a1" doxytag="PAtomicInteger::IsZero"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> BOOL PAtomicInteger::IsZero </td> <td class="md" valign="top">( </td> <td class="mdname1" valign="top" nowrap> </td> <td class="md" valign="top">) </td> <td class="md" nowrap> const<code> [inline]</code></td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>Test if an atomic integer has a zero value.
