-- This package encapsulates all direct interfaces to OS services

-- PLEASE DO NOT add any with-clauses to this package
-- or remove the pragma Elaborate_Body.
-- It is designed to be a bottom-level (leaf) package.
-- This version is for POSIX-like operating systems
-- The original file "s-osinte.sm4" contains conditional
-- macro calls that allow selection of various options.
-- The options selected for this expansion were:
-- When adding new signals to s-osinte.sm4, don't forget to update
-- cconst.dat (m4 macro definition data-file) and the files
-- s-intnam.ads (package Ada.Interrupt_Names) for the various ports.
