#include <interop/dl/include/alpaqa/dl/dl-problem.hpp>

Detailed Description

Class that loads a problem using dlopen.

The shared library should export a C function with the name <symbol_prefix>_register that accepts a void pointer with user data, and returns a struct of type alpaqa_problem_register_t that contains all data to represent the problem, as well as function pointers for all required operations. See C++/DLProblem/main.cpp

Note: Copies are shallow, they all share the same problem instance, take that into account when using multiple threads.

See also: TypeErasedProblem

Examples: C++/DLProblem/main.cpp.
