_CorDllMain Function

Initializes the common language runtime (CLR), locates the managed entry point in the DLL assembly's CLR header, and begins execution.

Syntax

BOOL STDMETHODCALLTYPE _CorDllMain (  
   [in] HINSTANCE hInst,  
   [in] DWORD     dwReason,  
   [in] LPVOID    lpReserved  
);  

Parameters

hInst
[in] The instance handle of the loaded module.

dwReason
[in]Indicates why the DLL entry-point function is being called. This parameter can be one of the following values: DLL_PROCESS_ATTACH, DLL_THREAD_ATTACH, DLL_THREAD_ATTACH, or DLL_PROCESS_DETACH. For descriptions of these values, see the DllMain documentation in the Platform SDK.

lpReserved
[in] Unused.

Return Value

This method returns true for success and false if an error occurs.

Remarks

This function is called by the operating system loader for DLL assemblies. For executable assemblies, the loader calls the _CorExeMain function instead.

The operating system loader calls this method regardless of the entry point specified in the DLL file.

In Windows 98, Windows ME, Windows NT, and Windows 2000, the _CorDllMain function is called indirectly through a fixupin the operating system loader. In all other versions of Windows, it is called directly by the operating system loader.

For additional information, see the Remarks section in the _CorValidateImage topic.
