What is the best way to expose a callback API - C++
- by rursw1
Hi,
I have a C++ library that should expose some system\ resource calls as callbacks from the linked application. For example: the interfacing application (which uses this library) can send socket management callback functions - send, receive, open, close etc., and the library will use this implementation in stead of the library's implementation.
(This way enables the application to manage the sockets by itself, can be useful).
This library has to expose also more callbacks, like, for example, a password validation, so I wonder if there is a preferred method to expose the callback sending option in one API.
Something like:
int AddCallbackFunc (int functionCallbackType, <generic function prototype>, <generic way to pass some additional arguments>)
Then within my library I will assign the callback to the appropriate function pointer according to the functionCallbackType parameter.
Is there any way to implement it in a generic way which will fit ANY function prototype and ANY additional arguments?
Your help will be more than appreciated...
Thanks!
