|
|
-- This package contains types and procedures for interfacing to the
|
| 35 |
|
|
-- underlying OS. It is used by the GNAT compiler and by tools associated
|
| 36 |
|
|
-- with the GNAT compiler, and therefore works for the various operating
|
| 37 |
|
|
-- systems to which GNAT has been ported. This package will undoubtedly grow
|
| 38 |
|
|
-- as new services are needed by various tools.
|
| 39 |
|
|
|
| 40 |
|
|
-- This package tends to use fairly low-level Ada in order to not bring in
|
| 41 |
|
|
-- large portions of the RTL. For example, functions return access to string
|
| 42 |
|
|
-- as part of avoiding functions returning unconstrained types.
|
| 43 |
|
|
|
| 44 |
|
|
-- Except where specifically noted, these routines are portable across all
|
| 45 |
|
|
-- GNAT implementations on all supported operating systems.
