The pthread_getschedparam( ) function shall retrieve the scheduling policy and scheduling parameters for the thread whose thread ID is given by thread and shall store those values in policy and param, respectively. The priority value returned from pthread_getschedparam( ) shall be the value specified by the most recent pthread_setschedparam( ), pthread_setschedprio( ), or pthread_create( ) call affecting the target thread. It shall not reflect any temporary adjustments to its priority as a result of any priority inheritance or ceiling functions. TSP If _POSIX_THREAD_SPORADIC_SERVER is defined, then the policy argument may have the value SCHED_SPORADIC, with the exception for the pthread_setschedparam( ) function that if the scheduling policy was not SCHED_SPORADIC at the time of the call, it is implementation-defined whether the function is supported; in other words, the implementation need not allow the application to dynamically change the scheduling policy to SCHED_SPORADIC. The sporadic server scheduling policy has the associated parameters sched_ss_low_priority, sched_ss_repl_period, sched_ss_init_budget, sched_priority, and sched_ss_max_repl. The specified sched_ss_repl_period shall be greater than or equal to the specified sched_ss_init_budget for the function to succeed; if it is not, then the function shall fail. The value of sched_ss_max_repl shall be within the inclusive range [1,{SS_REPL_MAX}] for the function to succeed; if not, the function shall fail. If successful, the pthread_getschedparam( ) and pthread_setschedparam( ) functions shall return zero; otherwise, an error number shall be returned to indicate the error. The function never returns EINTR.
