Once the library is loaded I can obtain a pointer to the function using GetProcAddress() I want to call the function with the arguments specified on the command line. Can I pass a void-pointer-list to the function-pointer which I got returned by the LoadLibrary() function simi...
Now, I'm aware that there is a requirement for function pointers to be compatible as discussed in this question, but I'm not sure whether having an argument of different pointer type satisfies that compatibility requirement. The code compiles and runs, but, as expected, gives warni...
I have in the past written code for templated functions where one function argument can be either a function pointer or a Functor. Works pretty straightforward. Now I am in a situation where I am actually trying to pass a function pointer as template argument to a class. Unfortunately thi...

prototyped function through a prototypeless pointer? So long as it's a function that could be defined without a prototype, it doesn't matter whether it actually is. This means void f1() {} void f2(void) {} void f3(c) char c; {} void f4(char c) {} void f5(i) int i; {} ...

Often, you can simply pass a MATLAB variable (passing an argument by value), even when the signature for that function declares the argument to be a pointer. There are times, however, when it is useful to pass alib.pointer. You want to modify the data in the input arguments. ...
