Is there such a thing as a generic function pointer in C that can be assigned/casted to a more restrictive prototype?

Question

I have the need to dynamically link against a library at run-time and resolve a series of functions using dlsym. My first thought was to use an array of functio

Answer 1

You should probably define your list as void *functionList[2], since dlsym returns a void *. Once you know which function you have, you can cast it to the proper type.

void *functionList[2];

...

int (*functionA)(int) = (int(*)(int))functionList[0];
char (*functionB)(char,int) = (char(*)(char, int))functionList[1];
