What is the purpose of the `JNIEXPORT` keyword?
The `JNIEXPORT` keyword defines the signature of native methods that Java can use.
Thatâ€™s partially correct. `JNIEXPORT` is used to mark the method for export, but it does not define the method signature itself. The method signature is defined using the C function prototype.
Can you clarify how `JNIEXPORT` is related to the actual method implementation in C or C++?
