That depends on what you mean by "standard". I think you mean that all DLLs
have an entry point function, since it is a standard. Not all DLLs have a
DLL entry point. I am not guessing, I know that the DLL entry point is not
required.

Perhaps you are thinking that when other languages, such as C++, are used to
create a DLL, that the source code is generate with a DLL entry point
function. When using VC 6 and a "Win32 Dynamic-Link Library" project is
created, we have a choice of three options. One is to create a project
without any source code generated, another is a project with a simple DLL,
and another is a project for a DLL that exports symbols. The source code
generated for the simple DLL does have a skeleton DllMain and that is all
that is in the source code. The third type of project generates source code
with a DllMain that also has a switch (select) statement and it has a sample
class that exports a couple of functions.

The DllMain can of course be deleted in a second from the generated source
code if it is not needed.
