[Qemu-devel] vl.h: DisplayState's void functions

[Tim]

Hello,

Maybe this is a stupid question, but is there a reason why it would be
bad to change this struct's function pointers to accept functions which
return a value?  It might be good to allow the return of error
codes from these functions, or at least a boolean, and currently there
isn't a convenient way to do so.  Could they be changed to return an int
instead?

I can submit a patch for this, if y'all think it is a good idea.

thanks,
tim
