You'd do it the same way you do in C. On Windows, call
LoadLibrary, FreeLibrary, and GetProcAddress or the COM
functions. On Linux, the family of functions is dlopen, dlsym,
and dlclose.
Knowing the types to pass the functions is gonna be tricky and
this needs to be right to avoid crashes. On Windows with
scripting language, this is often done through COM automation:
the IDispatch interface. With regular C functions, you really
just have to know the prototypes ahead of time... it won't be
fully dynamic, you load the library at run time but know how to
use it at compile time.
That's the way I do it but I was wondering. Is it better to load
all the functions from the DLL at the start of the program or
load them when required and keep having to check if they're
loaded before each use?
