If no such pragma - -- appears, then the value Unspecified_Task_Info is passed. If a pragma - -- is present, then it supplies an alternative value. If the argument of - -- the pragma is a discriminant reference, then the value can be set on - -- a task by task basis by supplying the appropriate discriminant value. - - -- Note that this means that the type used for Task_Info_Type must be - -- suitable for use as a discriminant (i.e. a scalar or access type). - - ----------------------- - -- Thread Attributes -- - ----------------------- - - subtype CPU_Number is System.Win32.ProcessorId; - - Any_CPU : constant CPU_Number := -1; - - Invalid_CPU_Number : exception; - -- Raised when an invalid CPU number has been specified - -- i.e. CPU > Number_Of_Processors. - - type Thread_Attributes is record - CPU : CPU_Number := Any_CPU; - end record; - - Default_Thread_Attributes : constant Thread_Attributes := (others => <>); - - type Task_Info_Type is access all Thread_Attributes; - - Unspecified_Task_Info : constant Task_Info_Type := null; - - function Number_Of_Processors return Positive; - -- Returns the number of processors on the running host - -end System.Task_Info; |
