I've used DllMain as the DLL "main" since that's the most common
|
|
usage. MSVC and Mingw32 both default to DllMain as the standard
|
|
callback from the linker entry point. Cygwin, as of b20.1, also
|
|
uses DllMain as the default callback from the entry point.
|
|
|
|
The real entry point is typically always defined by the runtime
|
|
library, and usually never overridden by (casual) user. What you can
|
|
override however is the callback routine that the entry point calls,
|
|
and this file provides such a callback function, DllMain.
|
|
|
|
Mingw32: The default entry point for mingw32 is DllMainCRTStartup
|
|
which is defined in libmingw32.a This in turn calls DllMain which is
|
|
defined here. If not defined, there is a stub in libmingw32.a which
|
|
does nothing.
|
|
|
|
Cygwin: The default entry point for Cygwin b20.1 or newer is
|
|
__cygwin_dll_entry which is defined in libcygwin.a. This in turn
|
|
calls the routine DllMain. If not defined, there is a stub in
|
|
libcygwin.a which does nothing.
|
|
|
|
MSVC: MSVC runtime calls DllMain, just like Mingw32.
|
|
|
|
Summary: If you need to do anything special in DllMain, just add it
|
|
here. Otherwise, the default setup should be just fine for 99%+ of
|
|
the time. I strongly suggest that you *not* change the entry point,
|
|
but rather change DllMain as appropriate.
