| -- This package implements Calendar.Time delays using protected objects. |
| |
| -- Note: the compiler generates direct calls to this interface, in the |
| -- processing of time types. |
| |
| package Ada.Calendar.Delays is |
| |
| procedure Delay_For (D : Duration); |
| -- Delay until an interval of length (at least) D seconds has passed, |
| -- or the task is aborted to at least the current ATC nesting level. |
| -- This is an abort completion point. |
| -- The body of this procedure must perform all the processing |
| -- required for an abortion point. |
| |
| procedure Delay_Until (T : Time); |
| -- Delay until Clock has reached (at least) time T, |
| -- or the task is aborted to at least the current ATC nesting level. |
| -- The body of this procedure must perform all the processing |
| -- required for an abortion point. |
| |
| function To_Duration (T : Time) return Duration; |
| |
| end Ada.Calendar.Delays; |
