mfb_update after window closes kills julia

[rafaqz]

Might be nice to catch that somehow so it just throws an error.

Is there a way of checking the window is still open, or can we set a callback for when it closes?

Is this on linux? On windows, mfb_update returns correctly when called on a closed window

julia> state = mfb_update(window, g_buffer)
STATE_EXIT::mfb_update_state = -1

I have the same issue on Linux

[rafaqz]

Yes it's on linux, sorry I should have specified that.

Unlike the other issue #10 I can close the window fine with Ctl-C, Julia only dies when you run mfb_update.

This is on Arch, with kernel 5.8.5-arch1-1

I also have this problem on my system.Clicking the close button while the window is updating kills the REPL.

Ctrl-C stops the update of the window but doesn't close the window. Clicking the close button after Ctrl-C doesn't cause the REPL to crash.
