Hello,
I would like to build a small interpreter (in an c-program), which calls
functions with user-defined arguments.
To do this, I have a list of functions names (in an array), with the
pointers to the function (in an external library). The user-supplied
arguments I got as Strings, which i have to transform to the right type
(adresses,...

The library function 'qsort' is declared thus:
void qsort(void *base, size_t nmemb, size_t size,
int(*compar)(const void *, const void *));
If in my code I write:
int cmp_fcn(...);
int (*fcmp)() = &cmp_fcn;
qsort(..., fcmp);
then everything works. But if instead I code qsort as:

C++ App.
The C++ app creates the Dict using the following functions:

Is it possible to pass a pointer to a constructor or a class definition
as argument to a function? Maybe in a way similar to passing function
pointers...?
The function should construct a number of objects using the given
constructor. The objects should all inherit from a base class.
It's not possible to pass actual objects, since it's not...

Hello lads,
I'd like to do the following in C:
1. The user writes a function with predefined arguments and return value in a separate file.
2. The program is compiled as my written 'main' program and the file containing the user function included.
3. When the program is invoked, the user is asked how his function is named (f.e. function1)....
