package Safe_Support is
-- Ada tasking safe and abort safe file I/O support.
--
-- All sequential_io, direct_io, text_io, integer_io, float_io,
-- fixed_io and enumeration_io file operations are wrapped
-- by the services file_lock() and file_unlock(). The user
-- is guaranteed atomic operations on a per task basis.
-- Furthermore, the task initiating the I/O request is inhibited from being
-- completed by an Ada Abort until it finishes.
--
-- The remaining lock() and unlock() services protect
-- data structures shared across multiple files.
-- Initialize/destroy the file's lock mutex
