This limit includes both the pre-created sprocs and -- those explicitly created under program control. function Sproc_Stack_Size return Integer; -- The size, in bytes, of the sproc's initial stack function Default_Time_Slice return Duration; -- The default time quanta for round-robin scheduling of threads of -- equal priority. This default value can be overridden on a per-task -- basis by specifying an alternate value via the implementation-defined -- Task_Info pragma. See s-tasinf.ads for more information. function Default_Task_Stack return Integer; -- The default stack size for each created thread. This default value can -- be overridden on a per-task basis by the language-defined Storage_Size -- pragma. function Stack_Guard_Pages return Integer; -- The number of non-writable, guard pages to append to the bottom of -- each thread's stack. function Pthread_Sched_Signal return Integer; -- The signal used by the Pthreads library to affect scheduling actions -- in remote sprocs. function Pthread_Arena_Size return Integer; -- The size of the shared arena from which pthread locks are allocated. -- See the usinit(3p) man page for more information on shared arenas. function Os_Default_Priority return Integer; -- The default Irix Non-Degrading priority for each sproc created to -- service threads. end System.Program_Info;
