|library(registry): Manipulating the Windows registry|
library(registry) is only available on the
MS-Windows version of SWI-Prolog. It loads the foreign extension
providing the predicates described below. This library only makes the
most common operations on the registry available through the Prolog
user. The underlying DLL provides a more complete coverage of the
Windows registry API. Please consult the sources in
pl/src/win32/foreign/plregtry.c for further details.
In all these predicates, Path refers to a `/' separated
path into the registry. This is not an atom containing
`/'-characters as used for filenames, but a term using the functor
Windows defines the following roots for the registry:
prolog.type. Name is the name visible in the Windows file-type browser. Finally, OpenAction defines the action to execute when a file with this extension is opened in the Windows explorer.
