Registering MvTCP File Descriptors to an External Main Loop

If you want to run your own main loop, you have to incorporate MvTCP file descriptors with it and call a predefined function to process the data received by these file descriptors.

If you want to be notified when MvTCP creates or deletes file descriptors,
use the functions SetCreateFDCallback and SetRemoveFDCallback to register the two callbacks.

When you detect an event in one of the MvTCP file descriptors, call the function ProcessFD to process the incoming data.

Note This method must be called after the MvTCP process has been initialized. When the function SetCreateFDCallback is called, Server immediately calls the callback you provided with the file descriptor used to listen for incoming connection requests.
