J.15.12 Pragma Relative_Deadline
Syntax
The form of a pragma Relative_Deadline is as follows:
pragma Relative_Deadline (relative_deadline_expression);
Name Resolution Rules
The expected type for a relative_deadline_expression is Real_Time.Time_Span.
Legality Rules
A Relative_Deadline pragma is allowed only immediately within a task_definition or the declarative_part of a subprogram_body.
Static Semantics
For an implementation that supports Annex D, a pragma Relative_Deadline specifies the value of the Relative_Deadline aspect (see D.2.6). If the pragma appears in a task_definition, the expression is associated with the aspect for the task type or single_task_declaration that contains the pragma; otherwise, the expression is associated with the aspect for the subprogram that contains the pragma.
