Unloading a DLL

You can unload a loaded DLL by using the -u switch:
/dll -u <filename>
You can browse the list of loaded DLLs by using:

$dll(N/filename) returns the Nth loaded DLL

mIRC will automatically unload a DLL if it is not used for ten minutes, or when mIRC exits.

You can also define an UnloadDll() routine in your DLL which mIRC will call when unloading a DLL to allow it to clean up.

int __stdcall UnloadDll(int mTimeout);

The mTimeout value can be:

0 UnloadDll() is being called due to a DLL being unloaded with /dll -u.

1 UnloadDll() is being called due to a DLL not being used for ten minutes. The UnloadDll() routine can return 0 to keep the DLL loaded, or 1 to allow it to be unloaded.

2 UnloadDll() is being called due to a DLL being unloaded when mIRC exits.
