JNA (Java Native Access) is a Java library that allows Java programs to access native libraries written in languages such as C or C++. An "Invalid Memory Access" error typically occurs when a Java program uses JNA to access a native library and tries to read or write to a memory location that is not valid.
This error can have many causes, including passing incorrect parameters to the native library function, using a null pointer, or accessing memory that has already been freed. To fix this error, you should review your JNA code and ensure that you are using correct parameters and handling memory correctly.
You can also use tools such as Valgrind or GDB to debug native code and identify the source of the error. Additionally, using JNA's memory allocation and management functions can help prevent invalid memory access errors.
