[mixed programming JNI] Part 12 jnaerator

If a worker wants to do a good job, he must sharpen his tools first , We can write simple functions manually , But it's a little too much for me to write complex structures by myself

, This mode of production is a little low , And it may be wrong , After all, machines are more reliable than people

This section introduces JNA Tools for jnaerator, Free you from cumbersome and complex signatures

jnaerator Origin

Project address ：GitHub - java-native-access/jna: Java Native Access

JNA send Java Programs can easily access native shared libraries , No need to write Java Anything other than code - Unwanted JNI Or native code .

Java The call looks like a call in native code . Most calls do not require special handling or configuration ; No template files or generated code are required .

Used by developers Java Interface to describe the functions and structures in the target local library . This makes it very easy to take advantage of native platform features

JNA jar Package download address ： jna -5.10.0.jar jna-jpms-5.10.0.jar

This is a JNA Core artifacts for , Contains only binding libraries and core helper classes .

JNA platform

jna -platform-5.10.0.jar jna-platform-jpms-5.10.0.jar

This artifact contains cross platform mapping and mapping of many common platform functions , Including a large number of Win32 Mapping and a set of utility classes that simplify native access . The code has been tested , The utility interface ensures proper handling of native memory management .
