Call Function from Dynamic Library

Question

What would be the best way to, if possible, load a dynamic library and call one of it's functions, when we don't know the name of the function during compile-time?

For example, is there a way to make a program that reads a string from a file and then loads a DLL and searches for and calls a function with its name being the string read from the file?

Help would be very much appreciated.

Answer 1

There is an example on Wikipedia of all places showing how to use the LoadLibrary() function at runtime. You will see that the function name is specified as a string. You would need to write the code to search for the function name and pass it to similar code.

On Linux you can do this with dlopen() and dlsym() functions.
