For a uni-processor, the lock algorithm is pretty simple. Lock(threadID) { Disable Interrupts If lo开发者_运维知识库ck is already owned by same thread{
I am writing a program using C.I want to have a mutex which can help me to run a new instance o开发者_如何学编程f a program in case the first instance of my program lost or stopped working.
Let\'s say I\'m programming in a threading framework that does not have multiple-reader/single-writer mutexes. Can I implement their functionality with the following:
I need to implement barrier synchronization between 2 threads using mutex (only). Barrier synchronization is that 2 threads will wait for each other to meet at predefined step before proceeding.
I\'m developing in Visual Studio 2008 C# for 64bit and I want to use to use a library which uses boost. So I wrote a wrapper in C++/CLI. I managed to target the error I get to
e.g. EnterCriticalSection ( cs ); LeaveCriticalSection ( cs ); I want to create a functi开发者_StackOverflow社区on locking it and release if invoke your function call or leave the object.
from the apple\'s \"Threading Programming Guide\" I\'ve read that \"The best way to avoid both deadlock and livelock situations is to take 开发者_运维知识库only one lock at a time\". If I prefer to us
I was able to solve this myself by reading a bit further, I was asuming that you should refer to Threads rather than to objects. It works now. :)
In Brian Goetz\'s book, Java Concurrency in Practice, his example of a Reentrant lock is pro开发者_高级运维grammed like this:
I have these lines of code: // index is an integer Mutex mutex = new Mutex(false, \"MUT开发者_如何学编程EX_PREFIX\" + index.ToString());
