    I really can't see why everybody is getting so excited about
bitwise exclusive or assignments, or making improbable claims for them. It's
not as if it were a new technique. :-(
 KK >    In a program, you might use it like this:
 KK > #define swap(a, b) ((b ^= (a ^= (b ^= a))))
    Since this text replacement (macro expansion) occurs in the preprocessor,
any discussion of relative speeds at run time is meaningless, isn't it? Bob's
comments about sequence points OTOH are what is important.
    Won't the memset(), memmove() &c functions (string.h) always be orders of
magnitude faster in operation anyway because they can make use of the
processor/memory intimacy that occurs only at machine level (block moves).

Write your reply.

assistant: Hey Victor,
    What Carey says is right. Most external events that generate interrupts
can occur at a maximum frequency. The shortest time interval between any two
consecutive events limits the amount of time available for your ISR to run
with interrupts off. For example receiving characters asynchronously over a
serial line at 9600 baud takes about 1 ms between characters (ca 25000 clock
cycles at 25 MHz, or about 3000 machine instructions). Take any longer and
you will start having overrun errors, not to mention making the whole program
I/O bound. :-(
Good luck,
Bill.

assistant: don't.
  IMO this is not the way to go about it.  It's almost never
advantageous to write logic to read a whole file into memory, since the
f...() file functions are already buffered.  By using setvbuf() to set a
large buffer, the file will be efficiently processed in large chuncks,
but you can still write the logic as though you're handling the file a
line at a time.
not
  Writing back to the same file presents all sorts of difficulities.
IMO it's hardly worth the trouble.  It's much easier to write the output
to a new file then delete the old file and rename the new file to the
old file name.

Write your reply.

assistant: Hi Victor,
You wrote to me:
I don't know the details, as I've only done it in pure C.
What you've written clarifies things a bit, but my comment still
stands. You do _NOT_ wait for an interrupt in an interrupt. There is no
guarantee that the required interrupt will occur before the interrupt
you are sitting in requires servicing again. You have to do it by
setting flags in global data space to show the status of the interrupts
that you can test.
I see in another message in the thread that you are doing much of your
processing inside the timer tick interrupt. This is potentially
dangerous, and you should only do what is _essential_ within a hardware
interrupt service routine. This should really be limited to
reading/writing data and setting/clearing status flags. With proper
design everything else can be done within the main program.
Why do you find it necessary to do so much within the timer tick
interrupt?

Write your reply.

assistant: Do this all the time at work.  There is however a configuration option that
dis/enables "Microsoft extensions" (being at home I forget where exactly the
option is) and this will produce errors for non-ANSI keywords such as "far",
"near", and "pascal".
Hope this helps ... Steve
