Please expain about Interrupts & Handlers?

A signal informing a program that an event has occurred. When a program receives an interrupt signal, it takes a specified action (which can be to ignore the signal). Interrupt signals can cause a program to suspend itself temporarily to service the interrupt. \nInterrupt signals can come from a variety of sources. For example, every keystroke generates an interrupt signal. Interrupts can also be generated by other devices, such as a printer, to indicate that some event has occurred. These are called hardware interrupts. Interrupt signals initiated by programs are called software interrupts. A software interrupt is also called a trap or an exception. \n\nPCs support 256 types of software interrupts and 15 hardware interrupts. Each type of software interrupt is associated with an interrupt handler -- a routine that takes control when the interrupt occurs. For example, when you press a key on your keyboard, this triggers a specific interrupt handler. The complete list of interrupts and associated interrupt handlers is stored in a table called the interrupt vector table, which resides in the first 1 K of addressable memory. \n\n  \n  \nA table of interrupt vectors (pointers to routines that handle interrupts). On PCs, the interrupt vector table consists of 256 4-byte pointers, and resides in the first 1 K of addressable memory. Each interrupt number is reserved for a specific purpose. For example, 16 of the vectors are reserved for the 16 IRQ lines. \nAn interrupt vector table is also called a dispatch table.

As a long-term programmer, I have worked for years before there were mainstream debuggers with compilers. A lot of embedded compilers also do not come with debuggers.\n\nPrint statements are the best possible way to debug in absence of a debugger. It's a pain, and you have to recompile all of the time, but it sure beats having no debug information at all!\n\nIf there is no monitor to which you may display print statements, then you can also use serial ports (connect the device to a PC that can run a serial comm program), LED's (blink them), and even speakers. I have used all in different situations.

an event handler is your program's response to the user's action.  for example if the user moves the mouse, you can have an event handler do something just because of that action.\nOnclick(), is the name of one event handler, when the user clicks on a graphic object you made, you have certain actions performed\nOnMouseMove(), OnFocus()...

Try and use an IDE if you can. Or switch to linux for programming, you wont have to use getch() or pause :)

ob_start();\n\nheader('some_header');\n\nob_end_flush();\n\nIf you place ob_start() at the beginning of your script nothing will be sent until you call ob_end_flush(). This way you can add your header() functions as you need them.

The inputs are received from hardware using "interrupts" or IRQs. An interrupt is very similar to you receiving an "interrupt" (i.e. doorbell) when someone is at the door. The cables/ports relay these interrupts to the PC.\n\nCheck out some assembly language books/device driver books for details.

Now, if only they would enable the user to input their OWN functions...that would be useful.  \n\nBTW, if anyone knows how to do that, I would surely like to know!

Presumably you don't have to do any I/O here, although you're not clear on that point. So, you have to compare registers AX and DX.  Then jump to the appropriate code to print out the right answer.  \n\nWhy don't you just look at  your notes and take a crack at it?  It's really not very hard, and I'm sure your instructor has reviewed the instructions you need to use.

Try a counter approach.\n\ngetDataObject()\n{\n  synchronized (this)\n  {\n    counter++;\n  }\n  if (!open) throw error;\n  try\n  {\n//  do stuff here...\n    return stuff;\n  }\n  finally\n  {\n    synchronized (this)\n    {\n      counter--;  // must decrement in sync block\n      notifyAll();\n    }\n  }\n}\n\nsynchronized close()\n{\n  // counter is guaranteed not to decrement\n  while (counter > 0)\n    wait();  // until here, so we won't miss the notifyAll from above!\n  open = false;\n}\n\nI deserve a beer for this I think...

An IRQ in your CPU is an interrupt.\nThe best analogy I heard is you put the kettle on then go off and do something else, watching telly etc; but as soon as the kettle clicks off, your up to pour your cuppa.\nNow substitute in CPU for yourself and the kettle for a program or piece of hardware. When the program or hardware generates an interrupt the CPU stop what it is doing and attends to the interrupt.

I'm telling u the main points (so far I've studied in OS)...\n\n(1).Windows XP operating system is a multithreaded kernel that provides support for both real-time applications 'n multiple-processors. \n\n(2).On uniprocessor system, when WinXP kernel access a global resource, it temporarily masks interrupts for all interrupt-handlers.\n\n(3). On multiprocessor system, WinXP protects access to global resources using spinlocks. (e.g.- in Solaris, kernel uses spinlocks to protect short-code segments).\n\n(4). For thread synchronization outside the kernel, WinXP provides dispatcher-objects. (several mechanisms 're there... mutexes, semaphores, events, timers etc.)\n\n(5). Dispatcher objects may be either in a 'signaled-state' or in a 'non-signaled-state'. 'Signaled-state' means -- an object is available & a thread won't block while acquiring the object. 'Non-signaled-state' means -- just the opposite (i.e. object's unavailable & thread'll block if tries to acquire that object)\n\nTransitions :\nnon-signaled-->(owner thread releases mutex-lock)-->signaled\nsignaled-->(thread acquires mutex lock)-->non-signaled\n- - - - -- - - -- - - - - - - - - - - - - - - - - - - - - - - - - \nWe've text book of O.S. by 'Silberschatz & Galvin'. Go through it, if possible. Otherwise visit Wikipedia... bye.

that is a simple read write, with a silly delay, and the buffering is turned off.... BUT...\n\ncgi isn't cgi isn't cgi! which server? modperl? fastcgi? weird config?\n\nUPDATE:\n\nhmm active state... a good port for a great webserver on an problematic O/S!\n\ntry something like "for ... print <img...>  in the loop, with a greater delay... does that work?\n\nperhaps the STDIN did not have more than 4096 chars in it!\n\nmy number 1 rule of debuggin' \nremove all but the problem and see if the problem goes away!
