问题 How to use monitors in PHP? 回答1: I might be wrong but i thought that the server side model of execution of php is single threaded (aka no more than one thread). In fact i think this is one of reasons of PHP's success. If this is the case i doubt is relevant how do you use synchronization primitives in php. 回答2: PHP is single threaded so there is no need for synchronization. 回答3: PHP is single threaded, but if you want to have something like mutex between different processes and you use PHP5,

问题 the issue I'm having is that upon executing this code, it clicks, and then my monitor turns blue and says "HDMI no cable connected", and either returns back to normal after 1 second, or stays on that screen until I perform an action (click, alt etc). Anybody with any idea on why this is happening would be appreciated. #include "stdafx.h" #include <Windows.h> using namespace std; void function() { INPUT Input; Input.type = INPUT_MOUSE; Input.mi.dwFlags = MOUSEEVENTF_LEFTDOWN; SendInput(true,

问题 In Java, why is unlocking called ( lock.unlock() ) after calling signal ( notEmpty.signal() and notFull.signal() )? The order is reversed in pthread. So why is the difference? Thanks. From The Art of Multiprocessor Programming, 1 class LockedQueue<T> { 2 final Lock lock = new ReentrantLock(); 3 final Condition notFull = lock.newCondition(); 4 final Condition notEmpty = lock.newCondition(); 5 final T[] items; 6 int tail, head, count; 7 public LockedQueue(int capacity) { 8 items = (T[])new

问题 I have a simple snippet(not MVC) of code looking like the following # include <Cocoa/cocoa.h> int main(argc, *argv[]) { [NSApplication sharedApplication] [NSEvent addGlobalMonitorForEventsMatchingMask:NSKeyUpMask handler:^(NSEvent *evt){ .... }] [NSApp run] } When compiled as command line binary and run, the global event monitoring works, after allowing the program from system preferences -> privacy & security; then I packed it int an .app, and ran it, the global monitor stopped working even

问题 I've got a code like this: Some of our clients receiving "System.ArgumentNullException in System.Threading.Monitor.Enter" in the following code block: Public Class CheckStuff Private Shared SLock As New Object Public Sub GetIt() Synclock SLock DoSomething() End Synclock End Sub End Class How can this be possible? Considering the SLock is shared, never touched from anywhere else? 回答1: My guess is that you've oversimplified your sample code - it must be touched from something else to make it

问题 As part of an application for a client, I need to have a section which reports temperature information (motherboard, CPU, HDD). I know there are standalone applications such as Hardware Monitor by CPUID, but again, these are standalone and I require something that I could interface with. Is there any app like this which has an API or is open source so I can utilize their source code? I have language preferences other than it needs to run on Windows XP. Thanks. 回答1: You get info like this from

问题 Monitor.Pulse and PulseAll requires that the lock it operates on is locked at the time of call. This requirement seems unnecessary and detrimental for performance. My first idea was that this results in 2 wasted context switches, but this was corrected by nobugz below (thanks). I am still unsure whether it involves a potential for wasted context switches, as the other thread(s) which were waiting on the monitor are already available for the sheduler, but if they are scheduled, they will only

问题 I have tried this Windows example Getting WMI Data from a Remote Computer and this other Calling a Provider Method, and both work correctly in my computer. However I have tried to use WMI to change the brightness and I am getting an error on step 6, in this part: //Get the Next Object from the collection hres = pEnum->Next(WBEM_INFINITE, //Timeout 1, //No of objects requested &pObj, //Returned Object &ulReturned /*No of object returned*/); pEnum is a negative value. IMPORTANT: While I was
