NAME
     pthreadsetschedprio - dynamic thread scheduling  parameters
     access

SYNOPSIS
     cc -mt [ flag... ] file... -lpthread [ library... ]
     #include 

     int pthreadsetschedprio(pthreadt thread, int prio);


DESCRIPTION
     The  pthreadsetschedprio()  function  sets  the  scheduling
     priority  for  the thread whose thread ID is given by thread
     to the value given by prio.


     If the pthreadsetschedprio() function fails, the scheduling
     priority of the target thread is not changed.

RETURN VALUES
     If successful, the pthreadsetschedprio()  function  returns
     0;  otherwise,  an  error number is returned to indicate the
     error.

ERORS
     The pthreadsetschedprio() function will fail if:

     EINVAL    The value of prio is invalid  for  the  scheduling
               policy of the specified thread.


     EPERM     The caller does not have the  appropriate  permis-
               sion to set the priority to the value specified.


     ESRCH     The value specified by thread does not refer to an
               existing thread.
