dg_pthread_get_lwpid(3T)       DG/UX R4.11MU05      dg_pthread_get_lwpid(3T)


NAME
       dgpthreadgetlwpid - translate a thread ID to an LWPID

SYNOPSIS
       #include <pthread.h>
       #include <sys/types.h>

       lwpidt dgpthreadgetlwpid(pthreadt thread);

   where:
       thread Thread ID to be translated

DESCRIPTION
       This function returns the kernel-level LWPID corresponding to the
       thread ID given by thread.

       In DG/UX, every thread has a corresponding (efficient) kernel-level
       LWP.  Hence it is possible to retrieve, in a non-portable way, the
       LWPID for a given thread ID.  LWPIDs are reported by the nps(1)
       command and by calls to dglwpinfo(2).

DIAGNOSTICS
   Returns
       The dgpthreadgetlwpid() function returns the corresponding LWPID.

SEE ALSO
       dglwpinfo(2), nps(1), pthreadcreate(3T), pthreadself(3T).

NOTES
       In the current DG/UX implementation, the thread ID is the same as the
       corresponding LWPID.  However, applications should not make any
       assumptions about this relationship holding up in the future.

       Refer to <sys/intd6pthread.h>, <sys/dglwp.h> and
       pthreadself(3T) NOTES for a more detailed discussion on proper use
       of thread IDs and LWP group IDs.
