This is a very simple class to make dynamic library loads simple and easy. This code should multi-platform. The library gets automatically cleaned up and ice::Exception is thrown when an error occurs.
#include <ice/ice.h>
try
{
ice::Library lib("foo");
ice::Function<int (int, int)> func(&lib, "foofunc");
int i = func(2, 5);
}
catch (ice::Exception& ex)
{
// ex.whatString() will look similar to this:
// Failed to Retrieve address of function 'foofunc': Windows Error #0 for 'foo'
}
// lib and func auto clean up when they go out of scope
Using Library Manager:
#include <ice/ice.h>
try
{
// Init the library and call a function
std::cout << "Testing LibraryManager...\n";
auto mgr = ice::LibraryManager::instance();
mgr.add("myLibrary", "myLibrary.dll");
ice::Function<int (int, int)> myAdditionFunction(mgr["myLibrary"], "myAdditionFunction);
std::cout << "2 + 2 = " << myAdditionFunction(2, 2) << "\n";
// Throw an exception when we have an invalid library
mgr["nope"].getPath();
}
catch (ice::Exception& ex)
{
std::cout << ex.what() << "\n";
return 1;
}
// lib and func auto clean up when they go out of scope
// Output:
Testing LibraryManager...
2 + 2 = 4
LibraryManager Failed to retreive 'nope' From loaded library list!
