Found the PHP manual, but did not find the cause of the problem. Specific as follows. Code one: the code to work properly '; ob_flush(); flush(); sleep(1);}?> Code two: code that does not work '; ob_flush(); flush();

ArticleDirectory Abstract: Abstract: In many cases, C ++ is used because of the efficient performance of the native code compiled by C ++ and the excellent concurrency capability of C ++. Parallel methods can be divided into

Here we add the synchronized keyword to the run () method, hoping to perform mutex access to the run method, but the result is not as expected. this is because synchronized locks this object, that is, the current running thread object itself. 10

Event objectThe time object also belongs to the kernel object, which contains a count, a Boolean value indicating whether the event is an automatic reset event or a manual reset event, another Boolean value indicating whether the event is in the

Each thread has its own signal shielding word, but the signal processing is shared by all threads in the process. This means that although a single thread can block some signals, when the thread modifies the processing behavior related to a certain

In fact, this is also a question asked during the interview: (I am here to commemorate it. Note: It is just a simple list. For detailed principles and analysis, see the relevant chapter of the third edition of CLR via C) 1. Use the thread pool to

Thread attributes-Scheduling Next let's take a look at the second thread attribute we might want to change: scheduling. Changing the scheduling attribute is similar to setting the separation attribute, but we can use two other functions to find

Pipeline (PIPE ):Used for communication between kinship processes (such as parent and child processes and sibling processes)A process writes data to the pipeline: the number of bytes written is smaller than pipe_buf, which is an atomic operation.

Fork () and vfork () Learning Through the previous sections, we learned about the concept of processes and the implementation of processes in Linux. In this section, we will learn how to create a process in Linux. I. Preface: By studying the

Some time ago, a friend needs to install lnmp on centos 6.5 x64 of a new server. He thinks that manual installation is time-consuming and he needs to write an installation script. Later, I helped him write an lnmp_install.tar.gz with a size of 55.3

As mentioned above, the critical section can be used for thread synchronization, and the event and mutex can also be used.  Thread events in Win32 APIs Handle hevent = NULL;   Void maintestfun { Hevent = createevent (null, false, false, null

Because sometimes OS X system sleep will automatically wake up, and then sleep, every other will automatically wake up, and constantly cut off the hardware power, and then plug in power, equal to a night to restart more than 100 times, Mac life can
