| -- 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; |
