Seems like this could just be
} while (false);
as I don't see any way the loop could go around more than once.
"while (true)" is the instruction available in the hardware, this isn't
a description of C code.
Correct. It is primarily intended to explain approximately an equivalent
for the underlying code and is intended to interpreted with a grain of
salt. It is really pseudo-code that looks a lot like C :).
I also wanted to use "while(true)" to explicitly indicate the actual
effect of the implicit "break" at the end of the "loop". With
"while(false)", you have to scratch your head to figure out why that
final "break" is there, because it ought not be needed in a
"while(false)" loop.
