Ch can interface with existing C/C++ libraries and call C/C++ functions from Ch script.<ref>{{cite journal | last = Wilson | first = Matthew | year = 2004 | title = Open-RJ and Ch | url = http://drdobbs.com/184401877?queryText=ChSDK | publisher = Dr. Dobb's Journal}}</ref>
As a C/C++ interpreter, Ch can be used as a scripting engine forand yourextension language for applications. The pointerPointers to arrayarrays or variables can be passed and shared in both binary C space-compiled and chCh scripting spacecontexts. ItOne extends your applications with a C compatible scripting language. Oneexample of thean embedded chCh scripting application is Mobile-C., Mobile-Cwhich has been used for collaborative visualization of distributed mesh model.<ref>{{cite journal | last = Cheng | first = Harry | year = 2009 | title = Speeding-Up Software Development Using Embedded Scripting | pages = 8-8 | url = http://drdobbs.com/architecture-and-design/212201774 | publisher = Dr. Dobb's Journal}}</ref><ref>{{cite journal|last1=Wang|first1=Li-rong | last2 = Bo | first2 = Yo|last3=Hagiwara | first3 = I | title = Mobile-C based agent management for collaborative visualization of distributed mesh model | url = http://ieeexplore.ieee.org/search/freesrchabstract.jsp?tp=&arnumber=5375178&queryText%3DMobile-C%26openedRefinements%3D*%26searchField%3DSearch+All | publisher = Computer-Aided Industrial Design & Conceptual Design, 2009.
