You actually can, by using dlsym(3) to resolve the symbol, cast it to the
appropriate function pointer and call it.
For example:
int (*myfunc)(int, int) = dlsym(RTLD_DEFAULT, myfunc_name);
if (myfunc)
printf(“%d”, myfunc(2, 3));
else
fprintf(stderr, “error: cannot resolve symbol: %s”, myfunc_name);
This works on all POSIX operating systems.
