Whereas all threads created via a call to pthread_create have a POSIX thread ID and thread state, the library ensures that any Win32 native threads that interact through the Pthreads API also generate a POSIX thread ID and thread state when and if necessary. This provides full <SPAN LANG="en-GB">reciprocity</SPAN> between Win32 and POSIX threads. Win32 native threads that generate a POSIX thread ID and state are treated by the library as having been created with the <B>PTHREAD_CREATE_DETACHED</B> attribute.</P> <P>Any Win32 native thread may call <B>pthread_self</B> directly to return it's POSIX thread identifier. The ID and state will be generated if it does not already exist. Win32 native threads do not need to call <B>pthread_self</B> before calling Pthreads-w32 routines unless that routine requires a pthread_t parameter.</P> <H2><A HREF="#toc3" NAME="sect3">Author</A></H2> <P>Xavier Leroy <Xavier.Leroy@inria.fr> </P> <P>Modified by Ross Johnson for use with <A HREF="http://sources.redhat.com/pthreads-win32">Pthreads-w32</A>.</P> <H2><A HREF="#toc4" NAME="sect4">See Also</A></H2> <P><A HREF="pthread_equal.html"><B>pthread_equal</B>(3)</A> , <A HREF="pthread_join.html"><B>pthread_join</B>(3)</A> , <A HREF="pthread_detach.html"><B>pthread_detach</B>(3)</A> , <A HREF="pthread_setschedparam.html"><B>pthread_setschedparam</B>(3)</A> , <A HREF="pthread_setschedparam.html"><B>pthread_getschedparam</B>(3)</A> . </P> <HR> <P><A NAME="toc"></A><B>Table of Contents</B></P> <UL> <LI><P STYLE="margin-bottom: 0cm"><A HREF="#sect0" NAME="toc0">Name</A> </P> <LI><P STYLE="margin-bottom: 0cm"><A HREF="#sect1" NAME="toc1">Synopsis</A> </P> <LI><P STYLE="margin-bottom: 0cm"><A HREF="#sect2" NAME="toc2">Description</A> </P> <LI><P STYLE="margin-bottom: 0cm"><A HREF="#sect3" NAME="toc3">Author</A> </P> <LI><P><A HREF="#sect4" NAME="toc4">See Also</A> </P> </UL> </BODY> </HTML>
