c++11 - Casting function pointer to functor in C++ -


i have function pointer type imported .hpp file. like:

typedef void (*pfn_func)(int i);

i want create functor of same type:

std::function<pfn_func>

but doesn't work. don't want solution like

std::function<void(int)>

because mt function pointer definition more complicated

you this:

std::function<std::remove_pointer<pfn_func>::type>

removing pointer void (*)(int) gives function type void(int).

for case of general callable, see is possible figure out parameter type , return type of lambda?
