You should initialize your run time when your library is loaded, and clean-up
when it is unloaded.
In your LibMain procedure, you should treat the case
	DLL_PROCESS_ATTACH:
and call the specific run time initialization there.
In the same way, you should handle:
	DLL_PROCESS_DETTACH:
and call the runtime cleanup routines.

This is just basic win32 programming. Read any documentation about dlls and
you will find this.
