Passing pointer of address

[Thiago Milczarek Sayão]

Hi,

I'm doing some wayland binding experiments with jextract and FFM.
So far, so good.

But there's one thing that could be better, or I am doing it wrong (Please,
excuse me if it's my mistake.).

The eglChooseConfig call expects the pointer of an address on the second
argument.
https://registry.khronos.org/EGL/sdk/docs/man/html/eglChooseConfig.xhtml

The below code works, but I feel it could be simpler. Maybe a call like
attributes.addressPointer() ?

MemorySegment eglDisplay = EGL.eglGetDisplay(display.getSegment());
eglBindAPI(EGL_OPENGL_API());

if (eglDisplay.equals(EGL_NO_DISPLAY())) {
    System.out.println("NO DISPLAY");
    return null;
}

if (eglInitialize(eglDisplay, MemorySegment.NULL, MemorySegment.NULL) == 0) {
    System.out.println("eglInitialize Failed");
    return null;
};

int[] attribs = {
    EGL_RENDERABLE_TYPE(),
    EGL_OPENGL_BIT(),
    EGL_SURFACE_TYPE(),
    EGL_WINDOW_BIT(),
    EGL_RED_SIZE(),
    8,
    EGL_GREEN_SIZE(),
    8,
    EGL_BLUE_SIZE(),
    8,
    EGL_ALPHA_SIZE(),
    8,
    EGL_NONE()
};

MemorySegment eglConfig = Arena.global().allocate(C_POINTER);
MemorySegment numConfigs = Arena.global().allocate(EGLint);
MemorySegment attributes = Arena.global().allocateFrom(EGLint, attribs);

if (EGL.eglChooseConfig(eglDisplay,
MemorySegment.ofAddress(attributes.address()), eglConfig, 1,
numConfigs) == 0) {
    System.out.println("eglChooseConfig Failed");
    return null;
}
