DP_RESUME(2-N)             SYSTEM CALLS            DP_RESUME(2-N)


NAME
     dp_resume -- resume a thread in the same MPPG


SYNOPSIS
     #include <sys/mppg.h>

     int dp_resume(int lnid, pid_t pid, id_t tid);


DESCRIPTION
     dp_resume  resumes  a suspended thread.  Both process of the
     target thread and the calling process  must  belong  to  the
     same MPPG.

     lnid  specifies  the logical node number to which the target
     thread belongs.

     pid specifies the process ID  in  which  the  target  thread
     exists.

     tid specifies the ID of the target thread.

     dp_resume fails if one or more of the following are true:

     [EINVAL]   The calling process does not belong to an MPPG.

     [EINVAL]   The  calling  process  has not changed the signal
                mode by dp_cntl(2).

     [ESRCH]    No logical node can  be  found  corresponding  to
                that specified by lnid.

     [ESRCH]    No  process  can  be  found corresponding to that
                specified by pid.

     [ESRCH]    No thread can  be  found  corresponding  to  that
                specified by tid.

     [EIO]      There  is  no response from the node in which the
                specified process exists.

NOTES
     tid must be a physical thread ID and this ID can  be  recog-
     nized only by the thread library.  In addition, the suspend-
     ing facility only refers to the thread library.   Therefore,
     this call cannot be used in general.
