this is great work, logging engine has been neglected for ages, Im sure someone was moaning about this issue (lost few lines) on IRC or maybe its just wishful thinking so I have a plausible excuse for professing my admiration :) |

Would this also potentially improve lost settings on closing? reference #1744 it was asked on IRC last night so i thought I'de mention it (it happens randomly in Linux) since settings only writen to disk on shutdown |

Not sure, depends on how KVIrc is closed. It's likely a separate issue. |
|
Ide like to merge this asap, so please can we have some feedback? |

May you cleanup the style to be more consistent? e.g. indent

Oops, will do.

When you do catch up after holidays and come to this bit, a nice touch would be a rebase against master when youre at it. ;)
so then can finally merge this.
SIGTERM is the standard way on POSIX for the OS to tell an application to close. It can be sent when the computer is shutting down or the user is logging off, as well as by the user, directly, or indirectly (e.g. by using a task manager). SIGINT is sent when the user presses Ctrl+C in a terminal window in which the program is running. In both of these cases, KVIrc should shut down cleanly, as if the user closed the main window. This implies flushing logs. By implementing SIGTERM and SIGINT handling on POSIX, this patch fixes the log files not being flushed on receiving such a signal, thus causing the last few lines to be lost.
