What is the difference between glEnable and glEnableClientState?

What is the difference between glEnable and glEnableClientState? Every time I need to set / disable the mode, I have to look at the link to find out which of them will accept it. Is there any general rule that says which modes go into which?

In addition to tibur's answer in practice, the only use of glEnableClientState and glDisableClientState is to enable / disable the built-in attribute arrays of a fixed function (e.g. GL_VERTEX_ARRAY , GL_NORMAL_ARRAY , ...). For all other states, you use glEnable and glDisable (or glEnableVertexAttribArray and glDisableVertexAttribArray for common vertex shader attributes).

glEnable are server-side and glEnableClientState are client-side. Think of the server side as the processor and the client side as your GPU. Globally, vertex arrays are client-only.

glEnable used for a set of states defined by OpenGL ARB, representing the internal state of the driver. glEnableClientState is a state that represents information that you more directly control. The only client state that existed to enable / disable were the old states of the vertex array. And they were exceeded by glEnable/DisableVertexAttribArray .

The difference does not really make sense, since the driver still controls all of this state.
