The Function Pointer back-end is an experimental proof-of-concept (however, it is used in some unit tests as a light-weight back-end).
This back-end allows the registration of C/C++ function pointers and uses template magic to auto-generate an XML description using the type information in the function signature. Many template specializations for certain parameter types are missing, hence this back-end will only work for a limited set of argument types. See the ctkCmdLineModuleBackendFunctionPointer class for more information.
See the \ref CommandLineModulesBackendFunctionPointer_API module for the API documentation.
