-- This package provides exported subprograms to be called at debug time to
-- measure stack usage at run-time.
-- Note: this package must be a child package of System.Stack_Usage to have
-- visibility over its private part; it is however part of GNARL because it
-- needs to access tasking features via System.Tasking.Debug and
-- System.Task_Primitives.Operations;
package System.Stack_Usage.Tasking is
procedure Report_All_Tasks;
-- Print the current stack usage of all tasks on stderr. Exported to be
-- called also in debug mode.
