<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. | |
