The entry point function DllMain() is the main callback interface for achieving this mechanism. We have to look into the prototype and description of arguments of DllMain()
BOOL APIENTRY DllMain( HANDLE hModule,
Return value: 0 for success, non zero for error.
APIENTRY tells the compiler that it is an external/exported function.
hModule - This is the instance handle of the Loaded DLL.
ul_reason_for_call - reason for calling this DllMain() from Win32 subsystem
lpReserved - reserved variable.
ul_reason_for_call can have the following values
From the argument value it is clear that ul_reason_for_call will have the value DLL_THREAD_ATTACH when a new thread attaches to the current process.
- DLL_PROCESS_ATTACH, value 1
- DLL_THREAD_ATTACH, value 2
- DLL_THREAD_DETACH, value 3
- DLL_PROCESS_DETACH, value 0
Also ul_reason_for_call = DLL_THREAD_DETACH when a thread terminates from the process.
