====

Vulkan/GL/GLES/EGL/GLX/WGL Loader-Generator based on the official specifications

for multiple languages.

Check out the [webservice for glad2](https://glad.sh) to generate the files you need!

**NOTE:** This is the 2.0 branch, which adds more functionality but changes the API.

Some languages are only available in the [glad1 generator](https://glad.dav1d.de).

## Examples

```c

#include 

// GLFW (include after glad)

#include 

int main() {

    // -- snip --

    GLFWwindow* window = glfwCreateWindow(WIDTH, HEIGHT, "LearnOpenGL", NULL, NULL);

    glfwMakeContextCurrent(window);

    int version = gladLoadGL(glfwGetProcAddress);

    if (version == 0) {

        printf("Failed to initialize OpenGL context\n");

        return -1;

    }

    // Successfully loaded OpenGL

    printf("Loaded OpenGL %d.%d\n", GLAD_VERSION_MAJOR(version), GLAD_VERSION_MINOR(version));

    // -- snip --

}

```
