| -- This package contains the definitions and routines used as parameters |
| -- to the run-time system at program startup for the SGI implementation. |
| |
| package System.Program_Info is |
| |
| function Initial_Sproc_Count return Integer; |
| -- |
| -- The number of sproc created at program startup for scheduling |
| -- threads. |
| -- |
| |
| function Max_Sproc_Count return Integer; |
| -- |
| -- The maximum number of sprocs that can be created by the program |
| -- for servicing threads. 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 overriden 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. |
