如何在C++/OpenGL中获取当前鼠标位置？

glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED);

double xpos, ypos;
glfwGetCursorPos(window, &xpos, &ypos);

std::cout << "Mouse position: (" << xpos << ", " << ypos << ")"<< std::endl;

#include <GLFW/glfw3.h>
#include<iostream>

void mouse_callback(GLFWwindow* window, double xpos, double ypos)
{
    std::cout << "Mouse position: (" << xpos << ", " << ypos << ")"<< std::endl;
}

int main()
{
    if (!glfwInit())
    {
        std::cout << "Failed to initialize GLFW"<< std::endl;
        return -1;
    }

    GLFWwindow* window = glfwCreateWindow(800, 600, "My Window", NULL, NULL);
    if (!window)
    {
        std::cout << "Failed to create GLFW window"<< std::endl;
        glfwTerminate();
        return -1;
    }

    glfwMakeContextCurrent(window);
    glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED);

    while (!glfwWindowShouldClose(window))
    {
        glClear(GL_COLOR_BUFFER_BIT);

        double xpos, ypos;
        glfwGetCursorPos(window, &xpos, &ypos);
        mouse_callback(window, xpos, ypos);

        glfwSwapBuffers(window);
        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}
