Re: [Dev-C++] A Plugin Engine for my Application

[Per W. <pw...@ia...>]

Too little information given.

You can load plugin modules as DLL files - one or more plugins/DLL.

You will have a hard time protecting your program from ending if the
plugin is badly written. Windows kills broken programs, not broken
plugins. Maybe you can run the individual plugins as separate programs,
but then you must check into shared memory, sockets etc for
sending/receiving data between main program and plugin.

You haven't written anything about how much data each plugin needs to do
it's work. You haven't mentioned how long running time a plugin may
require for a call. You haven't specified expected # of calls/time unit.
You haven't discussed any requirements for concurrent operation of
multiple plugins, or how long time a plugin may consume before returning
(potentially with an answer).

The paragraph "To be clear" is most definitely not clear. It almost sounds
like you are talking about a driver layer either interfacing below the
Win32 API, or between the Win32 API and the plugins. But too little
details and no information about what problem you want to solve.
