--- 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.
