CLIPS with lock support. CLIPS for safely handling simultaneous access
CLIPSwl is a modified project based on CLIPS(C Language Integrated Production System)(https://sourceforge.net/projects/clipsrules/), a public domain open-source software tool for building expert systems.
CLIPS(ver. 6.24) is unsafe when access simultaneously occurs at the same environment,
because the environment data of CLIPS are not protected for simultaneous access.
We modified the CLIPS (ver. 6.24) to support lock/unlock functions in a flexible way.
CLIPSwl doesn't use complicated logic such as platform-independent mutex,
but newly defines 4 abstract functions (i.e. using function pointers) for allocating, acquiring, releasing and deallocating locks of the environment data.
