Boost converter (boost)The boost converter (boost) is the only option when the input voltage needs to be converted to a higher output voltage.The boost converter uses the internal MOSFET to charge the voltage to achieve the purpose of the

Boost::icontain consumption performance of the main reasons to see the source code, found mainly in the internal make a number of is_equal () calls, and each time is_equal will be to_upper () or to_lower () operation. So it is recommended to use the string's own find w

Boost. Asio c ++ network programming translation (26), boost. asio Network ProgrammingBoost. Asio-Other Features This chapter describes some features that Boost. Asio is not so well known. Standard stream and streambuf objects are sometimes more difficult to use, but as you can see, they also have their benefits. Finally, you will see the late

Next to boost, I will describe boost: datetime time processing. In C ++, the common time is time_t, filetime, and TM, while ptime is used in boost. Construct ptime 1. ptime constructor has four types: 1: using namespace boost::posix_time; 2: using namespace boost::

Boost. Asio c ++ network programming translation (20), boost. asio Network ProgrammingThe Asynchronous Server chart is quite complex. From Boost. Asio, You can see four arrows pointing to on_accept, on_read, on_write, and on_check_ping. That means you never know which asynchronous call is the next complete call, but you can be sure that it is one of the four oper

Use the method first to give the semaphore initialization assignment, you can set the desired value as needed, before writing the project in the process of using this control to download the number of threads.1 boost::interprocess::interprocess_semaphore M_semaphore (0);Then is the PV operation, v operation only one post (), post () once, the semaphore plus 1.P operation has three, see the function name is clearly know what meaning,Wait (), try_wait (

The header file is the libraryThe most common question for users is "How should I install boost", which is also my biggest concern at the beginning. Boost is doing well and encapsulates most of the implementations in the header file, therefore, some basic boost libraries do not need to be installed. You only need to include the header files in your own programs,

20130811 wcdj When many developers hear the term 'event process', they will think of the GUI: click a button and the associated functions will be executed. Click itself is an event, and the function is the corresponding event processor. Of course, this mode is not limited to Gui. In general, any object can call special functions based on specific events. This chapter introducesThe boost. Signals Library provides a simple method to apply this mode in

IntroductionThere is few information about what to compile boost with Intel compiler. This article are to describe a simple command steps to let you get a boost library with Intel compiler support.StepsStep 1:start your Intel compiler cmd window Start your Intel cmd window from "Start-and Intel Parallel Studio XXX--click the environment your need." step 2:change The directory to

1. mutex object class Mutex has two types: exclusive and shared mutex.▲Exclusive mutex:Mutex: exclusive mutex, which is the simplest and most commonly used mutex type.Try_mutex: it is a synonym for mutex, provided to be compatible with previous versionsTimed_mutex: it is also an exclusive mutex, but provides the timeout lock function.▲Recursive mutex:Recursive_mutex: recursive mutex, which can be locked multiple times and unlocked multiple times accordinglyRecursive_try_mutex: it is a synonym fo

look at the following example: Namespace {boost: mutex io_mu; void to_interrupt (const STD: string Str) {// If this_thread-> interrupt () is called outside the thread () // The following checkpoints in the thread can throw the boost: thread_interrupted exception try {boost: this_thread: disable_interruption (); For (INT I = 0; I Running result: 2013-01-02 11:

Boost is a quasi-standard library, which is equivalent to the continuation and expansion of STL. Its Design Concept is similar to that of STL, and it uses generics to maximize reuse. However, boost is more practical than STL. STL is concentrated inAlgorithmAnd boost contains a lot of tool classes, you can do more specific work.
