`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.


API documentation
-----------------

Open the [../../docs/library_index.html#os](../../docs/library_index.html#os)
link in a web browser.


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.
