Server provides an API to register a function callback using a function pointer. Client has to implement that function and the address reference has to be passed to server.
Server registers this function pointer as event callback and calls the same as the events are generated. This design is applicable for C or non-OOP languages. Events or callback functions are member functions of this class and client creates an object and implements these events and passes the address reference of the object to the server.
This callback class can have n-number of event functions and thus server can call any event as needed. This design eliminates the need of registering individual functions to the COM server. We are taking an imaginary minimal class to understand this events. Active 8 years, 2 months ago. Viewed times. Add a comment. Active Oldest Votes. See stackoverflow.
