-- Operating system interface facilities
-- This package contains types and procedures for interfacing to the
-- underlying OS. It is used by the GNAT compiler and by tools associated
-- with the GNAT compiler, and therefore works for the various operating
-- systems to which GNAT has been ported. This package will undoubtedly grow
-- as new services are needed by various tools.
-- This package tends to use fairly low-level Ada in order to not bring in
-- large portions of the RTL. For example, functions return access to string
-- as part of avoiding functions returning unconstrained types.
-- Except where specifically noted, these routines are portable across all
-- GNAT implementations on all supported operating systems.
-- See file s-os_lib.ads for full documentation of the interface
with System.OS_Lib;
package GNAT.OS_Lib renames System.OS_Lib;
