Is possible to build a function C/C++ call dynamically? I.e, i have an array with pointer functions and these functions can have different number of parameters and types. These parameters and their types are stored in a database that i'll get depending on the function name that i want to execute with a function pointer.

More or less i want to build a function thrower with any parameter.

Can i build the function call dynamically?

Any idea?
Hello
you can also implement virtual function in C++.
you give some definition of function in the base class and declare it virtual and then give another defintion with/without the same signature in the child class.
This excludes static binding and the function relevant to the data would be called dynamically at runtime. But it does seem a litttle bloated.
I would have a look at the C++ reflection library . Seems interesting though.
Regards.
