I have just been familiar with Android and Java platforms, but I still don't know much about JNI. So I have reposted an article from csdn so that I can understand JNI, I would also like to share with you.
JNIYesJava Native Interface. Since Java 1.1,
After learning C language for so long, I did not expect to have a good understanding of the common printf functions in C language.
The following sections are available:
Set int arr [] = {6, 7, 8, 9, 10 };
Int * PTR = arr;
* (PTR ++) + = 123;
Preface
Programmers familiar with C know the usage of Union. Using union, they can use the same bucket to store different types of data, thus saving memory space. You can use "." and "->" to directly access members in the bucket. After C ++ appears,
Danny Kalev is the host of the C ++ section of informit.com, a slightly nervous and sensitive blogger that I admire and loyal to C ++. Today, he published an article on informit titled "Visual C ++ 8.0 hijacking C ++ standards ". I rushed to see
I have found a lot of information on the Internet. I believe there are many guys who prefer vc6.0 like me. Isn't the latest wdk really usable? Yes !!!
Before you start, you must clarify one thing. You can use wdk + notepad alone to develop a driver,
You may have been using VC to develop software, but you may not be familiar with this compiler. There are many reasons. In most cases, we only "use" it, instead of "Understanding" it. Because it is just a tool, we would rather focus more on the C ++

As you know, C ++ has a sound Exception Handling Mechanism, which is also supported by the C language. In addition, in many other modern programming languages, they also have their

In vc2005:

Now let's take a closer look at how to register a driver code and look at the following code:

You can specify or cancel frmt_vrt during compilation to control whether the statement is compiled into an
Java Native Interface Usage in Java
JNI is the abbreviation of Java Native Interface. Since Java 1.1, the Java Native Interface (JNI) standard has become part of the Java platform. It allows Java code to interact with code written in other languages.
I. Memory alignment
Many computer systems have limits on the locations where basic data is stored in the memory. They require that the first address value of the data be K (usually 4 or 8) this is the memory alignment, and this K is called the
Yesterday, I participated in the so-called "Programming Competition" C language testing organized by the college. There are three questions, which are very painful. The first question: the number of output values between 1 and 1000 that can be
