WITH Unix_Base_Types;
PACKAGE System_Interface IS
--
-- This package provides a C-like interface to Unix system calls.
-- This interface is a subset of Section 2 of the HP-UX Reference Manual.
-- See the manual for a full description of these calls.
--
-- All data types are similar to the C definitions. All subprograms are
-- implemented via the appropriate interface pragmas.
--
-- The package is organized as follows:
--
-- Error - error number constants
-- File_Access - file access operations
-- File_Io - primitive input/output operations
-- Ids - identifier and group operations
-- Process - process operations
-- Shell - shell (command line) operations
-- Sockets - socket operations
-- Time - timer operations
--
PACKAGE Error IS
-- Errno : Unix_Base_Types.Int;
-- PRAGMA Linkname (Errno, "errno");
-- the pragma linknames takes subprograms only, so we build a
-- errno function
