<P><B>pthread_create</B> creates a new thread of control that
executes concurrently with the calling thread. The new thread applies
the function <I>start_routine</I> passing it <I>arg</I> as first
argument. The new thread terminates either explicitly, by calling
<A HREF="pthread_exit.html"><B>pthread_exit</B>(3)</A> , or
implicitly, by returning from the <I>start_routine</I> function. The
latter case is equivalent to calling <A HREF="pthread_exit.html"><B>pthread_exit</B>(3)</A>
with the result returned by <I>start_routine</I> as exit code.
</P>
<P>The initial signal state of the new thread is inherited from it's
creating thread and there are no pending signals. <B>Pthreads-w32</B>
does not yet implement signals.</P>
<P>The <I>attr</I> argument specifies thread attributes to be applied
to the new thread. See <A HREF="pthread_attr_init.html"><B>pthread_attr_init</B>(3)</A>
for a complete list of thread attributes. The <I>attr</I> argument
can also be <B>NULL</B>, in which case default attributes are used:
the created thread is joinable (not detached) and has default (non
real-time) scheduling policy.
</P>
<H2><A HREF="#toc3" NAME="sect3">Return Value</A></H2>
<P>On success, the identifier of the newly created thread is stored
in the location pointed by the <I>thread</I> argument, and a 0 is
returned. On error, a non-zero error code is returned.
