on some platforms (e.g.
glibc 2.2.x), there are bugs in the dl* functions, and the workaround is to not call dlclose. Setting this variable to 0 will cause dlclose to never be called. Doing this has some problems: memory mapped to the shared library will never be freed up. New versions of the library can't be loaded (if a provider is updated)

Derived classes have to override this function to implement the symbol loading.
The symbol to be looked up is contained in functionName, and the pointer to the function should be written into *fp. Return true if the function succeeded, false otherwise.
- Parameters:
-
functionName The name of the function to resolve. fp Where to store the function pointer.
- Returns:
- true if function succeeded, false otherwise.
Implements BLOCXX_NAMESPACE::SharedLibrary.
