|
* Returns an instance of \ref imported_class which allows to call or import more functions.
|
|
* It takes a copy of the smart_libray, so no added type_aliases will be visible,
|
|
* for the object.
|
|
*
|
|
* Few compilers do implement an allocating constructor, which allows the construction
|
|
* of the class without knowing the size. That is not portable, so the actual size of the class
|
|
* shall always be provided.
|
|
*
|
|
* \b Example:
|
|
*
|
|
* \code
|
|
* auto import_class<class type_alias, const std::string&, std::size_t>(lib, "class_name", 20, "param1", 42);
|
|
* \endcode
|
|
*
|
|
* In this example we construct an instance of the class "class_name" with the size 20, which has "type_alias" as an alias,
|
|
* through a constructor which takes a const-ref of std::string and an std::size_t parameter.
|
|
*
|
|
* \tparam T Class type or alias
|
|
* \tparam Args Constructor argument list.
|
|
* \param lib Path to shared library or shared library to load function from.
|
|
* \param name Null-terminated C or C++ mangled name of the function to import. Can handle std::string, char*, const char*.
|
|
* \param mode An mode that will be used on library load.
|
|
*
|
|
* \return class object.
|
|
*
|
|
* \throw boost::system::system_error if symbol does not exist or if the DLL/DSO was not loaded.
|
|
* Overload that accepts path also throws std::bad_alloc in case of insufficient memory.
