218 -- Default_Sized_SS_Pool : System.Address;
219 -- Binder_Sec_Stacks_Count : Natural;
220 -- XDR_Stream : Integer;
222 -- Main_Priority is the priority value set by pragma Priority in the main
223 -- program. If no such pragma is present, the value is -1.
225 -- Time_Slice_Value is the time slice value set by pragma Time_Slice in the
226 -- main program, or by the use of a -Tnnn parameter for the binder (if both
227 -- are present, the binder value overrides). The value is in milliseconds.
228 -- A value of zero indicates that time slicing should be suppressed. If no
229 -- pragma is present, and no -T switch was used, the value is -1.
231 -- WC_Encoding shows the wide character encoding method used for the main
232 -- program. This is one of the encoding letters defined in
233 -- System.WCh_Con.WC_Encoding_Letters.
235 -- Locking_Policy is a space if no locking policy was specified for the
236 -- partition. If a locking policy was specified, the value is the upper
237 -- case first character of the locking policy name, for example, 'C' for
240 -- Queuing_Policy is a space if no queuing policy was specified for the
241 -- partition. If a queuing policy was specified, the value is the upper
242 -- case first character of the queuing policy name for example, 'F' for
245 -- Task_Dispatching_Policy is a space if no task dispatching policy was
246 -- specified for the partition. If a task dispatching policy was specified,
247 -- the value is the upper case first character of the policy name, e.g. 'F'
248 -- for FIFO_Within_Priorities.
250 -- Priority_Specific_Dispatching is the address of a string used to store
251 -- the task dispatching policy specified for the different priorities in
252 -- the partition. The length of this string is determined by the last
253 -- priority for which such a pragma applies (the string will be a null
254 -- string if no specific dispatching policies were used). If pragma were
255 -- present, the entries apply to the priorities in sequence from the first
256 -- priority. The value stored is the upper case first character of the
257 -- policy name, or 'F' (for FIFO_Within_Priorities) as the default value
258 -- for those priority ranges not specified.
260 -- Num_Specific_Dispatching is length of the Priority_Specific_Dispatching
261 -- string. It will be set to zero if no Priority_Specific_Dispatching
262 -- pragmas are present.
264 -- Restrictions is the address of a null-terminated string specifying the
265 -- restrictions information for the partition. The format is identical to
266 -- that of the parameter string found on R lines in ali files (see Lib.Writ
267 -- spec in lib-writ.ads for full details). The difference is that in this
268 -- context the values are the cumulative ones for the entire partition.
270 -- Interrupt_States is the address of a string used to specify the
271 -- cumulative results of Interrupt_State pragmas used in the partition.
272 -- The length of this string is determined by the last interrupt for which
273 -- such a pragma is given (the string will be a null string if no pragmas
274 -- were used). If pragma were present the entries apply to the interrupts
275 -- in sequence from the first interrupt, and are set to one of four
276 -- possible settings: 'n', 'u', 'r', 's', see description in init.c
277 -- (__gnat_get_interrupt_state) for further details.
279 -- Num_Interrupt_States is the length of the Interrupt_States string. It
280 -- will be set to zero if no Interrupt_State pragmas are present.
282 -- Unreserve_All_Interrupts is set to one if at least one unit in the
283 -- partition had a pragma Unreserve_All_Interrupts, and zero otherwise.
285 -- Exception_Tracebacks is set to one if the -Ea or -E parameter was
286 -- present in the bind and to zero otherwise. Note that on some targets
287 -- exception tracebacks are provided by default, so a value of zero for
288 -- this parameter does not necessarily mean no trace backs are available.
290 -- Exception_Tracebacks_Symbolic is set to one if the -Es parameter was
291 -- present in the bind and to zero otherwise.
293 -- Detect_Blocking indicates whether pragma Detect_Blocking is active or
294 -- not. A value of zero indicates that the pragma is not present, while a
295 -- value of 1 signals its presence in the partition.
297 -- Default_Stack_Size is the default stack size used when creating an Ada
298 -- task with no explicit Storage_Size clause.
300 -- Default_Secondary_Stack_Size is the default secondary stack size used
301 -- when creating an Ada task with no explicit Secondary_Stack_Size clause.
303 -- Leap_Seconds_Support denotes whether leap seconds have been enabled or
304 -- disabled. A value of zero indicates that leap seconds are turned "off",
305 -- while a value of one signifies "on" status.
307 -- Main_CPU is the processor set by pragma CPU in the main program. If no
308 -- such pragma is present, the value is -1.
310 -- Default_Sized_SS_Pool is set to the address of the default-sized
311 -- secondary stacks array generated by the binder. This pool of stacks is
312 -- generated when either the restriction No_Implicit_Heap_Allocations
313 -- or No_Implicit_Task_Allocations is active.
315 -- Binder_Sec_Stacks_Count is the number of generated secondary stacks in
316 -- the Default_Sized_SS_Pool.
318 -- XDR_Stream indicates whether streaming should be performed using the
319 -- XDR protocol. A value of one indicates that XDR streaming is enabled.
