<h4><a name="tag_13_36_08"></a>CHANGE HISTORY</h4>

<blockquote>
<p>First released in Issue 5. Included for alignment with the POSIX Threads Extension.</p>
</blockquote>

<h4><a name="tag_13_36_09"></a>Issue 6</h4>

<blockquote>
<p>The RTT margin markers are broken out into their POSIX options.</p>

<p>The Open Group Corrigendum U021/9 is applied, correcting the prototype for the <a href=
"../functions/pthread_cond_wait.html"><i>pthread_cond_wait</i>()</a> function.</p>

<p>The Open Group Corrigendum U026/2 is applied, correcting the prototype for the <a href=
"../functions/pthread_setschedparam.html"><i>pthread_setschedparam</i>()</a> function so that its second argument is of type
<b>int</b>.</p>

<p>The <a href="../functions/pthread_getcpuclockid.html"><i>pthread_getcpuclockid</i>()</a> and <a href=
"../functions/pthread_mutex_timedlock.html"><i>pthread_mutex_timedlock</i>()</a> functions are added for alignment with
IEEE&nbsp;Std&nbsp;1003.1d-1999.</p>

<p>The following functions are added for alignment with IEEE&nbsp;Std&nbsp;1003.1j-2000: <a href=
"../functions/pthread_barrier_destroy.html"><i>pthread_barrier_destroy</i>()</a>, <a href=
"../functions/pthread_barrier_init.html"><i>pthread_barrier_init</i>()</a>, <a href=

"../functions/pthread_spin_unlock.html"><i>pthread_spin_unlock</i>()</a>.</p>

<p>PTHREAD_RWLOCK_INITIALIZER is deleted for alignment with IEEE&nbsp;Std&nbsp;1003.1j-2000.</p>

<p>Functions previously marked as part of the Read-Write Locks option are now moved to the Threads option.</p>

<p>The <b>restrict</b> keyword is added to the prototypes for <a href=

"../functions/pthread_sigmask.html"><i>pthread_sigmask</i>()</a>.</p>

<p>IEEE PASC Interpretation 1003.1 #86 is applied, allowing the symbols from <a href=
"../basedefs/sched.h.html"><i>&lt;sched.h&gt;</i></a> and <a href="../basedefs/time.h.html"><i>&lt;time.h&gt;</i></a> to be made
visible when <i>&lt;pthread.h&gt;</i> is included. Previously this was an XSI extension.</p>

<p>IEEE PASC Interpretation 1003.1c #42 is applied, removing the requirement for prototypes for the <a href=
"../functions/pthread_kill.html"><i>pthread_kill</i>()</a> and <a href=
"../functions/pthread_sigmask.html"><i>pthread_sigmask</i>()</a> functions. These are required to be in the <a href=
"../basedefs/signal.h.html"><i>&lt;signal.h&gt;</i></a> header. They are allowed here through the name space rules.</p>

<p>IEEE PASC Interpretation 1003.1 #96 is applied, adding the <a href=
"../functions/pthread_setschedprio.html"><i>pthread_setschedprio</i>()</a> function.</p>

<p>IEEE&nbsp;Std 1003.1-2001/Cor&nbsp;1-2002, item XBD/TC1/D6/13 is applied, correcting shading errors that were in contradiction
with the System Interfaces volume of IEEE&nbsp;Std&nbsp;1003.1-2001.</p>
