1. Basic Ideas ①. Create a database with a locked application (field: _id,packagename), and if the application is locked, maintain the lock-applied package name into the database ②. Lock + unlocked = All applications in mobile phone (appinfoprovider) 2. Locked and unlocked data adapters Class Myadapter extends baseadapter{private Boolean islock; /** * @param islock is used to differentiate between l

In the previous example, we could "use the SQLite offline storage API to store the app's settings". We also show how to store the JSON we need in a local file in the example "How to dynamically modify the data in the Listmodel in the QML application and store it in JSON format". In this article, we will use the localstorage provided by Qtquick to store the data we need.To illustrate the problem, I'll start by creating a template based on the "QtQuick App with QML UI (qmake)". First we revise our

There are several ways, one is to download the source of their own compilation, generally to build the environmentFirst, compile or download the official website arm-pi.tar.gzThe official website has Raspberry Pi compiled arm version, I personally prefer 0.10.25, and there is no arm-pi version, the latest only support to 0.10.28, Hand wood ahYou have to configure the.

installation package we have produced to the cell phone or emulator. Note that the name of the click Package we produced above contains " all" to indicate that it is an installation package that applies to both the phone and the simulator. We open a terminal and enter the following command: liuxg@liuxg:~/downloads$ ADB push Wqqcom-uii.liu-xiao-guo_0.1_all.click/home/phablet Immediately thereafter, we entered the following order: liuxg@liuxg:~

whole road car can not be on the road normal driving, the road is also blocked by cars. The whole traffic is paralyzed, and this is the "deadlock". The cause of the deadlock is that the car that caused the accident took up the critical resource of the road, so that other cars could not travel normally on the road.There are two reasons for a deadlock in the actual program: The same thread locks the mutex that has been locked again; Thread A locks the mutex while waiting for the mute

Tags: Linux Pthread_mutex_lock Pthread_mutex_lock (pthread_mutex_t * mutex ); Int pthread_mutex_trylock (pthread_mutex_t * mutex ); Int pthread_mutex_unlock (pthread_mutex_t * mutex ); Description: The pthread_mutex_lock () function locks the mutex object specified by mutex. If mutex is locked, the thread that calls this function is blocked until mutex is available. This is the same as the mutex object specified by the mutex parameter returned by the function. At the same time, the call t

Lock and unlockWhen you use a logical lock to lock table entries, the system automatically writes records to the lock table.When you call the FM to set the lock, if the lock parameters parameter is not specified, the system locks the entire table. Of course, lock para

pthread_mutex_trylock (). No matter which type of lock, it cannot be obtained by two different threads at the same time, you must wait for unlocking. For common locks and adaptive locks, the locker can be any thread in the same process, and the error locks must be unlocked by the locker; otherwise, the EPERM is returned. for nested locks, the document and implementation requirements must be unlocked by the

The graph is represented in edges rather than adjacency matrix.

fourth parameter, which represents the expiration of key. In general, executing the Set () method above will result in only two results: 1. There is currently no lock (key does not exist), then the lock operation is performed, and the lock is set to an expiration date, and value represents the locked client. 2. There is a lock existing, do not do any operation. Cautious's children's shoes will be discovered, and our lock code satisfies the three conditions described in ou

1. Mutual exclusion Lock (volume) and condition variableBy default, mutexes and condition variables are used for inter-thread synchronization, and can be used for inter-process synchronization if they are placed in a shared memory area.1.1 Mutual exclusion Lock1. Overview:Mutexes (mutexes, also known as mutexes), prevent multiple threads from doing read and write operations on a common resource to ensure the integrity of the shared data.To protect critical sections to ensure that only one thread

. Why should we unlock it, think about it. If you don't unlock it, there will be no external permission to modify X and Y. If you want to modify these two values for the other two threads, You need to lock qclock. After thread 1 is ready, thread 2 will be run. Let's look at the thread function of thread 2. The function is also locked at the beginning, but when pthread_cond_wait of thread 1 is unlocked, it can continue to run, and, after that, it modif

means to release the resources it occupies, the lock is currently open. In Linux, mutex locks do not occupy any resources. Therefore, pthread_mutex_destroy () in linuxthreads has no action except checking the lock status (ebusy is returned when the lock status is locked. 2. mutex lock attributes The mutex lock attribute is specified when the lock is created. There is only one lock type attribute in the linuxthreads implementation. Different lock types are different when trying to lock a locked

answer is no. This is also illustrated by writing verification code. This gives me a greater interest in the re-entry lock, which is indeed a non-blocking lock. The following code may explain the problem: Four threads are running, and the current status of lock is printed before each running. Wait 5 seconds after running. Public static Void Main (string [] ARGs) Throws Interruptedexception { Final Executorservice exec = executors. newfixedthreadpool (4 ); Final Reentrantlock loc

The mutex has a reentrant, non-reentrant score. In the C + + standard library, a mutex is used to represent a non-reentrant mutex, and a recursive_mutex is used to represent a reentrant mutex. For these two classes to increase the ability to block threads based on time, there are two new mutex locks: timed_mutex (non-reentrant locks), Recursive_timed_mutex (reentrant locks).Mutexes are used solely for mutual exclusion of shared resources, that is, only one thread can use it at the same time to p

following table: Macro definition Function description Spin_lock_init (Lock) Initialize the spin lock and set the spin lock to 1, indicating that a resource is available. Spin_is_locked (Lock) If the spin lock is set to 1 (unlocked), 0 is returned, otherwise 1 is returned. Spin_unlock_wait (Lock) Wait until the spin lock is unlocked
