[Qemu-devel] [PATCH v2 1/5] vnc: pass bool parameter for some functions

[Qemu-devel] [PATCH v2 1/5] vnc: pass bool parameter for some functions

[liguang]

last parameters of vnc_listen_read,vnc_connect are bool,
so pass 'false/true' instead of '0/1' for them.

[Qemu-devel] [PATCH v2 5/5] ui: boolize 'full_screen'

[liguang]

full_screen parameter for functions sdl_display_init,
cocoa_display_init, curses_display_init should be
boolized by actual usage.
also boolize 'full_screen' in vl.c

it may be bold for cocoa, so if it hurts,
these changes can be dropped.

I think I'll apply my version instead, -- which converts remaining arguments
of functions your patch touches (so that we don't have this:

> -        vnc_connect(vs, csock, 0, 0);
> +        vnc_connect(vs, csock, 0, false);

where 3rd argument is also a bool), and which combines your patches 1/5
and 2/5 into one.

I'll resend it again in a top-level message.

Thanks,

So is is_waitconnect a booleand or integer? :)

How about this (I'm unsure about the author anymore ):

The same applies to no_frame, isn't it?

These conversions to bool are like this -- "thankless", because there are
so many of them all around, you touch one place and it becomes obvious
that nearby places should be touched too.  Like this:

This no_quit is bool too... :) But I think _this_ one might be in a
separate patch.  But it is also display-specific.

Besides, I think we should rewamp this display init thing entirely,
making displays to be modules and implementing options parsing
properly.

I think I'll do that today, and will convert these to bools while
at it.

Thanks,
