glfwTerminate

Signature

void glfwTerminate(void);

How it works

Call it once at the very end of the program. Windows you forgot to destroy are destroyed here, and so are their OpenGL contexts.

After glfwTerminate, no GLFW function works again until you call glfwInit once more. Any OpenGL object (buffer, texture, shader) belonged to a context that no longer exists, so delete them BEFORE this call if you want to free them cleanly.

Tips & pitfalls

• It is safe to call even when glfwInit failed: it then does nothing, because glfwInit already cleaned up after itself.

• Never call it from inside a GLFW callback.

Errors

When the call is invalid it does nothing and sets an error, which glGetError returns:

GLFW_PLATFORM_ERROR

The operating system or window system reported a failure; the description says which.

Example

1glDeleteVertexArrays(1, &vao);   // free GL objects while the context is alive
2glDeleteProgram(program);
3glfwDestroyWindow(window);
4glfwTerminate();
