.. _library_os:

os

This library entities define a portable operating-system interface for the supported backend Prolog compilers.

The os_types category defines some useful operating-system types for type-checking when using with the type library object.

Loading

To load all entities in this library, load the loader.lgt file:

::

| ?- logtalk_load(os(loader)).

Testing

To test this library predicates, load the tester.lgt file:

::

| ?- logtalk_load(os(tester)).

Known issues

Some predicates may only be supported by a subset of backend Prolog compilers on a subset of operating-systems. They should be used with care and fully tested in your application domain as some backend Prolog compilers have buggy and inconsistent interfaces, specially across operating-systems. See the remarks section in the os object documentation for details.
