If you literally need a variable that is visible to different subs in the same class (code-behind page in ASP.Net), what you are looking for is probably... .
Passing them as arguments is great, if the sequence of calls to the subs in question makes that feasible .

The function header for pthread_create looks like this:
int pthread_create(pthread_t * thread, const pthread_attr_t * attr, void * (*start_routine)(void *), void *arg);
I understand it all except that the function pointer for start_routine is of the form...

From the documentation for pthread_create :

From the spec :
If the start_routine returns, the effect is as if there was an implicit call to pthread_exit() using the return value of start_routine as the exit status.

The lpOverlapped function passed into ReadFileEx is passed into the lpCompletionRoutine... .
Since lpCompletionRoutine runs on the calling thread, you should be fine .
Just create a slot and store a pointer to whatever data you want .
You could use Thread Local Storage ...

Do you have a simple debounce routine handy to deal with a single switch input?
This is a simple bare metal system without any OS.
I would like to avoid a looping construct with a specific count, as the processor speed might fluctuate.

I am sure a general routine, or library must exists to do this, but I need to be able to show the user a "before" and "after" comparison of two versions of a string/text file.

I don't know of a VS plugin, but perhaps you're looking for something like Beyond Compare ?
I guess you are looking for a diff algorithm I would read diff and its algorithms .

Hi,
I added some additional code to the Linux kernel (the scheduler) and now I would like to know what is the impact of this modification.
For user processes I always used:

Now I am wondering if there is a...

I need an efficient commify filter or routine for use with Template::Toolkit. It is to be used many times on the page. It should support decimals.

This means that if you have on your page 10000 numbers... .
The commify function works on my desktop 130000 times per second on number like: "31243245356.4432" .
I think that if you are worried about speed of this - you are seriously misplacing your worries .
