Enums are not variables so they can be substituted directly for the corresponding value at compilation time. At least, this is how I understood it and the tests I did at that time were coherent with these assumptions.

How using an enum helps in saving memory space?

> “if int can represent all the values of the original type”.

could u plz explain with examples for both

int representing values of original type and
int not representing values of original type.

I had to modify my enableOSXVNC script to this (run as root) :

#!/bin/sh

/System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -verbose -activate -restart -agent -allowAccessFor -allUsers -privs -all -clientopts -setvnclegacy -vnclegacy yes -setvncpw -vncpw passwordYouWantToUse

Here’s the one to disable it

#!/bin/sh

/System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -verbose -deactivate

It’s probably the -setvnclegacy -vnclegacy yes that does the trick.

After following your advice of setting the password, I am able to connect to it. Many thanks.

I’m working on a new version where this will be possible, but I’m not sure when it will be available.

Right now BitPacket is quite simple and the performance is very slow. You might be interested to try a more robust library like construct.
