libepoxy is a library for managing OpenGL function pointers. It simplifies the process of loading and using OpenGL functions, abstracting away the complexities of different OpenGL versions and extensions. libepoxy automatically initializes OpenGL functions as they are used, making it easier for developers to write portable OpenGL applications.

“Epoxy is a library for handling OpenGL function pointer management for you.”

• **Automatic initialization:** libepoxy automatically initializes OpenGL functions as they are used, eliminating the need for manual function pointer loading.
• **Version and extension handling:** libepoxy seamlessly handles different OpenGL versions and extensions, ensuring compatibility across different platforms.
• **Function alias resolution:** libepoxy resolves function aliases, allowing developers to use a consistent set of function names regardless of the underlying OpenGL implementation.
• **EGL, GLX, and WGL support:** libepoxy supports multiple windowing systems, including EGL, GLX, and WGL, making it suitable for a wide range of OpenGL applications.

```c

1. include <epoxy/gl.h>

int main() {

   // No need to load OpenGL functions manually
   glClearColor(0.0f, 0.0f, 0.0f, 1.0f);
   glClear(GL_COLOR_BUFFER_BIT);

   // Use OpenGL functions as usual
   // ...

   return 0;

In this example, libepoxy automatically loads the `glClearColor` and `glClear` functions when they are first used. This simplifies the code and makes it more portable across different OpenGL implementations.
