By default, Windows Vista (more than 2000 systems) uses "soft affinity" (soft-related) operations to allocate threads to the CPU. This means that if other factors remain unchanged, the system tries to run the thread on the CPU where the thread was last run, so that data is retained in the cache of the CPU.
Hard affiinty is relative to soft affinity, which can be used to control which CPU runs and which threads.
During system boot, the system determine
The thread synchronization mechanism in user mode is highly efficient. If you need to consider thread synchronization, you should first consider the thread synchronization method in user mode.
However, user-mode thread synchronization is limited. For thread synchronization between multiple processes, the user-mode thread synchronization method is powerless. At this time, you can only consider using the kernel mode.
Windows provides many kernel object
Introduction
For a long time, programmers have used C and C ++ to develop Windows GUI applications. For many of us, this history can be traced back to the Windows 2.0 period. At that time, we used a C-based 16-bit Windows API, eve
Step 2: compile Java code
Next, we need to compile the Java code into bytecode.
One way to do this is to use the Java compiler javac provided with the SDK.
The command used to compile Java code into bytecode is:
CD TestJavac jni_javacallc_test.java
If the above Code is written in the eclipse environment, the above Java file is automatically generated under the bin of the project directory when the file is saved.
Step 3: Create a C/
First, create a C language source file test.c
void Swap (int* A, int* b)
{
int c = *a;
*a = *b;
*b = C;
}
Then download mingw64, unzip, go into the bin directory, see if there are gcc.exe, as long as the download is correct there are certain, you can add this bin directory to environment variables, you can run GCC anywhere. The lazy way is to dir

The operating system does not actually call the entry point function you have written. It calls the C/C ++ runtime startup function. This function is responsible for initializing the C/C ++ runtime database, so that you can call functions such as m a l o
A preemptible operating system (such as Microsoft Windows) must use an algorithm to determine how long the thread should be scheduled.
The thread Kernel Object of each thread maintains a context structure, which stores the register information and status of the thread last executed by the CPU. For every 20 ms, Windows can view all existing thread kernel objects. Only some of these objects can be scheduled.

Netbeans6.0 supports Java SE, Web Java EE, Mobility, UML, SOA, Ruby, and C/C ++, and covers almost all popular development languages and methods. it would be better to add support for PHP. additional configuration is required for C/C ++ support.

Step 1: Write Java codeStarting from writing a Java source code file, it will declare the local method (or method), load the shared library containing the local code, and then actually call the local method.

Directly use a text editor or create a project in ecilpos and type the following code:
Package test; public class jni_javacallc_test {// C/C ++ local method public native i
Condition variables -- condition variable is a newly added mechanism for processing thread synchronization issues in Windows Vista. It can be used with "critical section" or "srwlock" to synchronize threads, this is especially effective when implementing issues similar to "producer-consumer.
If there is no "product" available for "Consumer thread" (Reader thread), the "Consumer thread" should release the corresponding read/write lock or key code segme

Some data structures are maintained in the thread kernel object, including the context content "context", which contains some "CPU register information" in the context of the latest running condition of the thread ", it mainly includes an SP and an IP address, respectively saving the entry function addres

The first English character in sleep in VC is uppercase "S"
In standard C, sleep is used. Do not use uppercase letters. The following uses uppercas
The general way to learn C language is to first learn C and then C ++. It is best to have the basis of assembly language and microcomputer principles, followed by Visual C ++. This method takes a lot of time and endurance for learners. In school teaching, there is no time to thoroughly study the practical technology of

When programming in C ++, we sometimes get more room for programming, and to reduce code, we often use the plug-in assembly language for joint programming.
Below we practice embedding assembly in C ++ to implement DLL injection source code.

After the asynchronous I/O request is complete, you can receive a pointer in the overlapped structure. Generally, a C ++ class can be derived from the overlapped structure, and some other information can be added to the class to make it easier to process. Then, when using the readfile and writefile functions, you can pass the pointer of the C ++ Class Object. When I/O is complete and the stru
