The priority value returned from 8 pthread_getschedparam( ) shall be 9 the value specified by the most recent pthread_setschedparam( ), 10 pthread_setschedprio( ), or pthread_create( ) call affecting the 11 target thread. It shall not reflect any temporary adjustments to 12 its priority as a result of any priority inheritance or ceiling functions. 13 </assertion> 14 15 <assertion id="2" tag="ref:XSH6:33189:33199"> 16 TSP If _POSIX_THREAD_SPORADIC_SERVER is defined, then the policy argument may have the 17 value SCHED_SPORADIC, with the exception for the pthread_setschedparam( ) function 18 that if the scheduling policy was not SCHED_SPORADIC at the time of the call, 19 it is implementation-defined whether the function is supported; in other words, 20 the implementation need not allow the application to dynamically change the 21 scheduling policy to SCHED_SPORADIC. The sporadic server scheduling policy 22 has the associated parameters sched_ss_low_priority, sched_ss_repl_period, 23 sched_ss_init_budget, sched_priority, and sched_ss_max_repl. The specified 24 sched_ss_repl_period shall be greater than or equal to the specified 25 sched_ss_init_budget for the function to succeed; if it is not, then the function 26 shall fail. The value of sched_ss_max_repl shall be within the inclusive 27 range [1,{SS_REPL_MAX}] for the function to succeed; if not, the function 28 shall fail. 29 </assertion> 30 31 <assertion id="3" tag="ref:XSH6:33203:33204"> 32 If successful, the pthread_getschedparam( ) and pthread_setschedparam( ) 33 functions shall return zero; otherwise, an error number shall be returned 34 to indicate the error. 35 </assertion> 36 37 <assertion id="4" tag="ref:XSH6TC2:34057:34057"> 38 The function never returns EINTR. 39 </assertion> 40 </assertions> 41
