NAME    [Toc]    [Back]

     pthread_attr_setinheritsched, pthread_attr_getinheritsched	- thread
     scheduling	inheritance attributes

C SYNOPSIS    [Toc]    [Back]

     #include <pthread.h>

     int pthread_attr_setinheritsched(pthread_attr_t *attr, int	inherit);

     int pthread_attr_getinheritsched(const pthread_attr_t *attr,
	  int *inherit);

DESCRIPTION    [Toc]    [Back]

     By	default, a newly created thread	has its	scheduling attributes
     initialized from the attributes object used to create it (or from
     defaults if none is specified) [see pthread_create()].  As	an
     alternative, the new thread may inherit the current scheduling attributes
     from the thread which creates it.	The scheduling attributes which	may be
     inherited are the scheduling policy [see pthread_attr_setschedpolicy()]
     and scheduling parameters [see pthread_attr_setschedparam()].

     The pthread_attr_setinheritsched()	function sets the thread scheduling
     inheritance attribute in the object attr to the value of inherit.	The
     value must	be PTHREAD_INHERIT_SCHED if the	attributes are to be inherited
     or	PTHREAD_EXPLICIT_SCHED if the attribute	values are to be taken from
     the object	(this is the default).	The current scheduling inheritance for
     the attribute object attr,	is returned via	the inherit parameter of
     pthread_attr_getinheritsched().

DIAGNOSTICS    [Toc]    [Back]

     On	success	pthread_attr_setinheritsched() returns zero; otherwise an
     error number is returned:

     [EINVAL]	    The	value of inherit is neither PTHREAD_INHERIT_SCHED nor
		    PTHREAD_EXPLICIT_SCHED.

     pthread_attr_getinheritsched() always returns zero.
