       pthread_attr_setinheritsched,  pthread_attr_getinheritsched  -  set/get
       inherit-scheduler attribute in thread attributes object

       #include <pthread.h>

       int pthread_attr_setinheritsched(pthread_attr_t *attr,
                                        int inheritsched);
       int pthread_attr_getinheritsched(const pthread_attr_t *attr,
                                        int *inheritsched);

       Compile and link with -pthread.

       The pthread_attr_setinheritsched() function sets the  inherit-scheduler
       attribute  of  the  thread attributes object referred to by attr to the
       value  specified  in  inheritsched.   The  inherit-scheduler  attribute
       determines  whether a thread created using the thread attributes object
       attr will inherit its scheduling attributes from the calling thread  or
       whether it will take them from attr.

       The  following scheduling attributes are affected by the inherit-sched-
       uler  attribute:  scheduling  policy  (pthread_attr_setschedpolicy(3)),
       scheduling  priority  (pthread_attr_setschedparam(3)),  and  contention
       scope (pthread_attr_setscope(3)).

       The following values may be specified in inheritsched:

              Threads  that  are  created  using   attr   inherit   scheduling
              attributes  from  the creating thread; the scheduling attributes
              in attr are ignored.

              Threads that  are  created  using  attr  take  their  scheduling
              attributes from the values specified by the attributes object.

       The  default setting of the inherit-scheduler attribute in a newly ini-
       tialized thread attributes object is PTHREAD_INHERIT_SCHED.

       The  pthread_attr_getinheritsched()   returns   the   inherit-scheduler
       attribute of the thread attributes object attr in the buffer pointed to
       by inheritsched.

       On success, these functions return 0; on error, they return  a  nonzero
       error number.

       pthread_attr_setinheritsched() can fail with the following error:

       EINVAL Invalid value in inheritsched.

       POSIX.1-2001  also  documents  an  optional ENOTSUP error ("attempt was
       made  to  set   the   attribute   to   an   unsupported   value")   for

   Multithreading (see pthreads(7))
       The  pthread_attr_setinheritsched()  and pthread_attr_getinheritsched()
       functions are thread-safe.


       As at glibc 2.8, if a thread attributes  object  is  initialized  using
       pthread_attr_init(3),  then  the  scheduling  policy  of the attributes
       object is set to SCHED_OTHER and the scheduling priority is set  to  0.
       However,   if   the   inherit-scheduler   attribute   is  then  set  to
       PTHREAD_EXPLICIT_SCHED, then  a  thread  created  using  the  attribute
       object  wrongly  inherits  its  scheduling attributes from the creating
       thread.  This bug does not occur if either  the  scheduling  policy  or
       scheduling   priority   attribute  is  explicitly  set  in  the  thread
       attributes object before calling pthread_create(3).

       See pthread_setschedparam(3).

       pthread_attr_setschedpolicy(3), pthread_attr_setscope(3),
       pthread_create(3), pthread_setschedparam(3), pthread_setschedprio(3),
       pthreads(7), sched(7)
