Yes, that's exactly what it is, a MAC address. Thanks!

I have some strings that come in over a REST interface that represent some network coordinates. The string looks something like:

02:00:00:00:00:07

Bits 5 - 0 represent tier 1
bits 13 - 6...

I no longer think this is correct. How do I ensure that the function returns a boolean?

Thank you. This is very helpful. I can't seem to call Monitor, though. I get a lot of compilation errors.

I have




bool compare(int a, int b, int c)
{
return a == b == c;

But how do I know what parameters to pass into function() when I call it from monitor?

Basically, I have a function called "monitor" and basically, this function works by waiting until some expression is false, and then it returns.

Right now, for this specific instance, it compares...

Right. What you've said is probably a better way to describe the question. Using memcpy didn't seem very C++-ish to me, so that's why I asked.

Thanks.

>But since std::string (and any properly programmed type with allocated data) will have overloaded operator=, using = will work just fine, copying both the basic structure data and also creating new...

Basically the lines in question below are


queue[tail] = element;
vs.
memcpy(&queue[tail], &element, sizeof(T));

Too late. I fixed the problem. Your solution was useless.

Thanks for this. How does the initialization list help, though? It seems that "Stupid s" would still get created, then thrown away when the initialization list gets created... I supposed I can try it...

It seems like to avoid this thing from taking up memory, I need to do Stupid *s and then use s = new Stupid(size);

Am I correct?

Hmm. It seems like that it's destroyed when the Container object is destroyed. Effectively, it stays in memory despite not being used.

The situation I'm asking about is in the comments. Basically, when does "s" of type Stupid get cleared?



class Stupid
{
int size;
int *array;
public:
Stupid(){}

Default constructor is different than what you said. As I said, i removed it and got even different errors.

Removing it is not correct. It actually spits out a whole slew of errors now.

I don't think you can remove a constructor like this. I have actually reverted my code to a previous version where all...

Basically, when the compiler tries to link this stuff into a "simpletest" executable (the simpletest.cpp with a main isn't included but I can if needed) it says it can't reference the constructor of...

I did indeed read that, but that solution has an inherent race condition in it, which will certainly lead to buggy code.

Hi,

I am trying to play around with the mwait and monitor concepts on intel processors (I have a KNL machine so these instructions are available).

I can't, for the life of me, see how to...

Got it. Makes sense. For some reason, I thought there was some way I could play around with the | or something like that, but this macro works perfectly.

Ah, I THINK I see... so my "acquire_segment" function would have to take an additional parameter "int flag" or something that gets passed to COND. writer_acquire_segment(seg, 1) and...

Thanks. Sorry for the syntax error, I just quickly pasted something and forgot I was in the midst of changing the code before I pasted it.

The COND macro looks interesting but I must say I am a...

I have two blocks of code that I feel can be generalized. I have a reader_acquire_segment function and a writer_acquire_segment function and I feel that the bulk of the code could be generalized to...
