Difference between polling in examples

[lucky62 <lucky62@xxxxxxxxxx>]

Hello,

I am trying to understand how the polling functions work.
In the examples I see two different ways.


In the *ssh_client* example:
        the *connectors* are used
        connectors are attached to the event by *ssh_event_add_connector*
*ssh_event_dopoll*( event, *60000 *) is called

In the *sshd_direct-tcpip* example:
        custom struct *event_fd_data* is used
        this struct & socket & channel are attached to the event by 
*ssh_event_add_fd*
*ssh_event_dopoll*( mainloop, *100* ) is called


So the questions:
    What is the better way? (criteria: usage simplicity, speed, other?)
    How to tune the *timeout* in ssh_event_dopoll function? (Why there 
is the big difference between these examples?)


Thanks in advance
Jan
