Q.
I have a Clib-based NLM that exports some functions. The NLM has been made memory resident by doing ExitThread(TSR_THREAD,0). Now I want to port the same functionality into a LibC NLM. How would I do this?
A.
Use the following entry points for a library NLM:
entry: _LibCPrelude exit: _LibCPostlude
And add the following piece of code to your NLM:
#include <library.h>
#include <windows.h>
int DllMain (void *hinstDLL, unsigned
long fdwReason, void *lvpReserved)
{
#pragma unused(lvpReserved)
switch (fdwReason)
{
default:
return FALSE;
case DLL_NLM_STARTUP:
register_destructor((int) hinstDLL,
(int (*)(void *)) NULL);
return TRUE;
case DLL_NLM_SHUTDOWN:
case DLL_PROCESS_ATTACH:
case DLL_PROCESS_DETACH:
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_ACTUAL_DLLMAIN:
return TRUE;
}
return FALSE;
}
That's all you need for a library NLM. Now you can export every API you want from your NLM.
