Breaking from loop with commands

[DavidRBouter]

Hello,

I'm working with this library and i was wondering if there was some kind of way of breaking from the loop when the quit command is recieved. For example:

While(True){
ftpSrv.handleFTP();
if(Quitcommandrecieved()){//This function does not exist, is there a way to still do this?
break;
}
}
