One attribute object can be used in multiple calls to pthread_create(), with or without modifications between calls. The functions pthread_attr_setschedpolicy() and pthread_attr_getschedpolicy(), set and get the attribute in the attr argument related to the scheduling policy. The value for the aforementioned attribute can be SCHED_FIFO, SCHED_RR and SCHED_OTHER.RETURN VALUESIf successful, these functions return 0. Otherwise, an error number is returned to indicate the error. pthread_attr_getschedpolicy(), on success, will copy the value of the thread's scheduling policy attribute to the location pointed to by the second function parameter.ERRORSpthread_attr_getschedpolicy() will fail if: [EINVAL] Invalid value for attr. pthread_attr_setschedpolicy() will fail if: [EINVAL] Invalid value for attr. [ENOTSUP] Invalid or unsupported value for policy.SEE ALSOpthread_create(3), pthread_attr_init(3), pthread_attr_setschedparam(3), pthread_attr_setinheritsched(3)STANDARDSpthread_attr_setschedpolicy(), pthread_attr_getschedpolicy() conform to Version 2 of the Single UNIX Specification (``SUSv2'')BSDDecember 31, 2007 BSD
