Well, I wouldn't do that either, because you can't be sure what the compiler
is going to do with your code. You've got two expressions hooked together
with a logical 'and' -- now which one will the final code try first? The one
on the right? Uh-oh. This is better:
If((WinFont=(struct TextFont *)OpenFont(&ta))==NULL)
{
If((WinFont=(struct TextFont *)OpenFont(&ta))==NULL)
Abort("Can't open font\n");
}
That way, OpenFont() will always go first.
