of Unlocker that is different from other unlocking software is that it does not forcibly close the files that occupy the file, but unlocks it in a way that unlocks the file and program, and therefore does not cause the user's potential data to be lost, as is the case with other unlocking programs because of the forced closing of the program.Multi-language version, free to use.

to disambiguate between static and static method parameters (similar to what we did when we processed the instance properties and instance method parameters earlier).In general, any unqualified method and property name will come from another type-level method and property in this class. A type method can invoke the name of another type method in this class without prefixing the method name with the type name. Similarly, struct and enum type methods can also access static properties directly fro

command is to list all files in the all.tar package.-t indicates to list files. The tar-xf all.tar command is used to extract all files in the all.tar package.-x is used to unlock the files. The above is the most basic usage of tar. To help you compress or decompress files while packing and unpackage, tar provides a special feature. This means that tar can call other compression programs, such as gzip and bzip2, while packaging or unpacking. 1) tar calls gzip Gzipis a program developed by gnu

handle the deadlock accordingly. In addition, different types of mutexes do not deal with deadlocks, but the main thing is for programmers to pay attention to this in their own programming.4.3 Item variablesIn the previous section we talked about how to use mutexes to share and communicate data between threads, and one obvious disadvantage of mutexes is that it has only two states: locking and non-locking. The condition variable compensates for the lack of a mutex by allowing the thread to bloc

The file ending with .gz is the result of gzip compression. The decompress program relative to gzip is gunzip. Use the-z parameter in tar to call gzip. The following is an example: 　　 #

comes out again: waiting for the thread to call Pthread_cond_wait is still in possession of the mutex mutex, the next time the thread wants to wake up the thread will not be able to obtain mutex mutex, and then there is a deadlock. So before calling Pthread_cond_wait to put the current thread in wait, we should untie the mutex mutex, and when the thread wakes up and returns from the Pthread_cond_wait function, we should get the mutex mutex again.For example, like this:[CPP]View Plaincopyprint?

single player, but it can also store Game Information of multiple players on the same device. At the beginning of the game, all game levels (except level 1) were locked. Each time a player completes a level, it unlocks all players on the device. The LevelTracker struct uses static attributes and methods to monitor which level of the game has been unlocked. It also monitors the current level of each player. struct LevelTracker { static var highes

attention to this in programming. 4.3 condition VariablesThe previous section describes how to use mutex to share and communicate data between threads. One obvious drawback of mutex is that it has only two States: Lock and non-lock. Conditional variables make up for the lack of mutex lock by allowing the thread to block and wait for another thread to send signals. They are often used together with mutex locks. When a condition variable is used to block a thread, when the condition is not met, t

specifies a special file that needs to be protected, the system uses encryption to store the file on the hard disk. When the device is locked, your app is not even hacked to access this file. However, when the user unlocks the device, the app can make the decrypted file that was created to access the file. You can use different levels of data protection.Implementing data protection you need to consider how you want to create and manage the files you

destroy the mutex to free its occupied kernel resources. Destroying an already locked mutex will result in unpredictable consequences. the Pthread_mutex_lock function adds a lock to a mutex in the form of an atomic operation. If the target mutex is already locked, the Pthread_mutex_lock call will block until the mutex's possessor unlocks it. Pthread_mutex_trylock is similar to the Pthread_mutex_lock function, but it always returns immediately, regard

M is a model, but I prefer to say structure, and this model embodies the structural relationships between the elements of HTML. The encapsulated object forms a single reproductive family Atlas tree in the form of nodes, and each page element can be positioned exactly. two HTML and DOMThe following diagram explains the relationship between the two of them.we are not hard to see.

tar, which is the meaning of the undo. Tar provides a special feature to facilitate the user's ability to compress or decompress a file while unpacking the package. 　　This is what tar can call other compression programs while packaging or unpacking, such as calling Gzip, bzip2, and so on. 1) Tar call gzip gzip is a compression program developed by the GNU organization, and the. Gz end file is the result of gzip compression. The decompression procedure relative to Gzip is gunzip. Used in tar-Z T

succeeds, and then finds the data structure that describes the state of the resource to understand the resource situation. As soon as the resource is found to be busy, the thread turns to wait and unlocks the mutex, waits for the resource to be released, if the resource is idle, indicates that the thread can use the resource, then sets the resource to busy and unlocks the mutex.
