This function sets the swap interval for the current OpenGL or OpenGL ES context, i.e. the number of screen updates to wait from the time glfwSwapBuffers was called before swapping the buffers and returning. This is sometimes called vertical synchronization, vertical retrace synchronization or just vsync.
A context that supports either of the WGL_EXT_swap_control_tear and GLX_EXT_swap_control_tear extensions also accepts negative swap intervals, which allows the driver to swap immediately even if a frame arrives a little bit late. You can check for these extensions with glfwExtensionSupported.
A context must be current on the calling thread. Calling this function without a current context will cause a GLFW_NO_CURRENT_CONTEXT error.
This function does not apply to Vulkan. If you are rendering with Vulkan, see the present mode of your swapchain instead.
Parameters
interval: number
The minimum number of screen updates to wait for until the buffers are swapped by glfwSwapBuffers.
